Difference Between Organic and Inorganic Compounds

Organic compounds are extracted from living organism(plants,animals etc) and inorganic compounds are extracted from non living things(rocks,in laboratory etc).These days organic compounds can be artificially created by human beings, and moreover organic compounds have been found in outer space where there are no living beings.But this the difference which is very basic,in terms of chemistry their are lot of differences between Organic and inorganic compounds,lets discuss about them in detail.

Organic Compounds:-

Substance whose molecules contain one or more (often many more) carbon atoms covalent bonded with another element or radical(including hydrogen, nitrogen, oxygen, the halogens as well as phosphorus, silicon and sulfur).

A few exceptions are carbon monoxide, carbon dioxide, carbonates, cyanides, cyanates, carbides, and thyocyanates, which are considered inorganic.

Examples of organic compounds are carbohydrates, lipids, proteins and nucleic acids.

Inorganic Compounds:-

Any compound not containing carbon

atoms.

Any compound that containing carbon atoms ionically bound to other atoms.(carbon monoxide, carbon dioxide, carbonates, cyanides, cyanates, carbides, and thyocyanates).

Inorganic compound have salt forming capacity while organic compound do not form salts.

Organic compound have the molecules which contain carbon and hydrogen. Inorganic compound come mainly from mineral sources of non biological origin.

examples:- NaCl,H2,H2SO4 etc.

Difference Between Organic and Inorganic Compounds(Organic vs Inorganic Compounds):-

1. Organic compounds are extracted from living beings while inorganic compounds are created either due to natural processes or in the laboratory.

2. Inorganic compounds can make salt(as they are ionic), while organic does not due to their covalency.

3. Organic compounds contain carbon, while inorganic compound contain metal and other element.

4. Organic compounds have carbon-hydrogen bonds, while inorganic do not have these bond.

5. Inorganic compounds contain metal atoms, whereas organic compounds do not.

6. Organic compounds are biological and inorganic are mineral in nature.

7. Organic compound are covalent in nature whereas organic compound are both ionic and covalent in nature.

8.Organic compound can form long and complex chain of molecules(hence form polymers) whereas inorganic compound does not have this capacity.

9. Organic compound are source of energy for human life(as food) whereas inorganic compound act as catalyst.

10.Organic compound are used as main source of energy in modern world(as petroleum oil) whereas inorganic compound does not.

Difference between Ionic and Molecular compound

Difference between Ionic and Molecular Compound

Ionic and molecular compound are the two main variety of compound .Every thing in this world is either classified as ionic or molecular compound.The difference between ionic and molecular compound lies in the nature of bonding between the elements of the compounds.

Ionic Compound:-

Ionic compound are the compounds having the Ionic bond between its elements.

First we need to understand Ions to understand the Ionic bond.

Ion:-

An ion is an atom or molecule where the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge.

Ionic Bond:-

An ionic bond is a type of chemical bond that involves a metal and a non-metal ion (or polyatomic ions ) through electrostatic attraction. In short, it is a bond formed by the attraction between two oppositely charged ions.

The metal donates one or more electrons, forming a positively charged ion( or cation) with a stable electron configuration(completing its octate). These electrons then enter the non metal, causing it to form a negatively charged ion (or anion) which also has a stable electron configuration(completing its octate).The electrostatic attraction between the oppositely charged ions causes them to come together and form a bond.

Na + Cl → (Na+ ) +( Cl−) → NaCl

Molecular compound:-

Molecular Compound are also know as Covalent compound because they have covalent bond between its element.

Covalent Bond:-

Covalent bonds are the chemical bond in which pair of electrons are shared between the atoms and other covalent bond to fulfil its octate partially.

In the molecule H2, the hydrogen atoms share the two electrons via covalent bonding. Covalency is greatest between atoms of similar electro-negativities.

covalent bonding does not necessarily require the two atoms be of the same elements, only that they be of comparable electro-negativity.

Only covalent bond will be formed between atoms of same element.

Difference between Ionic and Molecular compound(Ionic and molecular compound):-

1)Ionic compound has Ionic bond between its elements whereas molecular compound has covalent bond between its element.

2)Ionic compound are good conductor of electricity in liquid or aqueous state whereas molecular are not.

3) ionic compounds are formed between metals and non-metals whereas Molecular compounds are formed between two non-metals.

4)Ionic compounds are always solid and crystalline in appearance whereas molecular compounds can be in any physical state – solid, liquid, or gas.

5)Ionic compound are found in lesser number then molecular compound.

6)Ionic compound formed when overall energy change for the reaction is favourable – when the bonded atoms have a lower energy than the free ones whereas the strength of covalent bond(of molecular compound) depends on the angular relation between atoms in polyatomic molecules.

Difference between Reflection and Refraction

Difference between Reflection and Refraction

Reflection and refraction are the phenomenon of waves in which wave changes its direction due to a change in its speed. For simplicity here we discuss difference between reflection and refraction for light rays only.

Reflection:-

When a ray of light falls on any surface, a part of the light is sent back to the same medium. This phenomenon where the incident light falling on a surface is sent back to the same medium is known as reflection.

Reflection of light follow laws of reflection.

Laws of reflection:-

1. The incident ray, the reflected ray and the normal to the reflection surface at the point of the incidence lie in the same plane.

2. The angle which the incident ray makes with the normal is equal to the angle which the reflected ray makes to the same normal.

3. Light paths are reversible.

Refraction:-

Refraction occurs when light waves travel from a medium with a given refractive index to a medium with another at an angle. At the boundary between the media, the wave’s phase velocity is altered, usually causing a change in direction. Its wavelength increases or decreases but its frequency remains constant.

Refraction of light follow Snell’s Law.

Snell’s Law:-

Refraction is described by Snell’s law, which states that the angle of incidenceθ1 is related to the angle of refraction θ2 by

Reflection and reflection are wonderful phenomenon which plays important role in our day to day life.

We can see our self into a mirror due to reflection of light. Reflection of light causes images turn left to right. Reflection is also used in solar furnaces where concave mirror is used to focus all the light ray into one point to rise the temperature. Moreover, reflection is also used in headlight of vehicles to focus the light and lighten the road at night.

Refraction play most important role as we can see through eye due to refraction by the lenses of our eyes. All the telescope are working on the principle of refraction. Spectacles are also based on refraction. Wherever the lenses are used(either convex or concave) refraction is there in action.

We should heard of Mirage in desert , which is also due to the refraction of light by the air which has different density as moving upward from the heated surface and hence have different refractive index.

Difference between Reflection and Refraction(Reflection vs Refraction)

1)Reflection is caused due to sending back of the light from different medium where as refraction is caused due to bending of light while travelling from one medium to another medium having difference in refractive index.

2)The angle of incidence and angle of reflection are the same in the case of reflection. These angles are not the same in refraction.

3)Mirrors(straight,concave or convex) are used in reflection whereas lenses(concave,convex or straight) are used in reflection.

4)Total internal reflection(eg. fish eye view) is the phenomenon which is the part of refraction.

Difference between Espresso and Latte

Espresso is the variation of coffee which is used all over the world and one of the basic form of coffee.Latte is prepared by adding more thing in espresso.Wondering about then?Lets discuss about them in detail.

Espresso:-

Café espresso, or just espresso is a concentrated coffee beverage brewed by forcing hot water under pressure through finely ground coffee.

Espresso has become increasingly popular in recent. In Northern Europe, specialty coffee chains have emerged, selling various sorts of espresso from street corners and high streets.

he first espresso machines were introduced at the beginning of the 20th Century, with the first patent being filed by Luigi Bezzera of Milan, Italy, in 1901.Presently,with popularity of home machines, espresso gains interest in very fast pace. Today, a wide range of home espresso equipment can be found in kitchen and appliance stores.

Espresso is used as the base of other drinks like mochas, macchiato, lattes and cappuccino.

Latte:-

Café latte is prepared by adding Espresso, a lot of milk and small dollop of milk foam (or froth).

The main difference between Espresso and Latte is the addition of milk and froth.

History of latte:-

Latte is invented by a Italian barista in the bay area in California named Lino Meiorin, he made truly Italian cappuccinos which were found by the local market as being too strong. So, Meiorin made adjustments making a cappuccino with larger portions of milk to lessen its strength. He called the drink café latte knowing that he only added more latte (milk) on the drink. The customers seemed to like it and soon it picked up and spread all across the world.

Espresso has more caffeine per unit volume of most beverages, compared on the basis of usual serving sizes, a 30 mL (1 fluid ounce) shot of espresso has about half the caffeine of a standard 180 mL (6 fluid ounce) cup of drip brewed coffee, which varies from 80 to 130 mg

In some places latte may be served in a glass instead of a cup. But, according to tradition, a espresso can be served in some kind of a porcelain cup that has greater heat-retention properties.

Difference between Espresso and Latte (Espresso vs Latte):-

1) Espresso is the base of many coffee variations whereas latte is one of the variations.

2) Espresso has only steamed water which is passed through finely grounded coffee beans whereas latte has espresso added with milk and froth (foamed milk).

Difference between Espresso and Cappuccino

Espresso is the most often available coffee.Espresso is one of the purest form of coffee,which is strong and very aromatic.Cappuccino is also one of the important item menu in cafes around the world.Lets discuss difference between espresso and cappuccino and find out more about them and their popularity.

Espresso:-

Caffè espresso, or just espresso is a concentrated coffee beverage brewed by forcing hot water under pressure through finely ground coffee.

Espresso is consumed in Italy and most parts of Europe. Superior coffee blends like Arabica and some times darker roasted beans are also used to make espresso to get stronger flavour. The brewing technique makes the espresso special. To prepare espresso, an espresso machine is needed.

The first espresso machines were introduced at the beginning of the 20th Century, with the first patent being filed by Luigi Bezzera of Milan, Italy, in 1901.Presently,with popularity of home machines, espresso gains interest in very fast pace.

Cappuccino is prepared by adding Espresso coffee, milk and lot of froth (milk Foam).

The main difference between Espresso and Cappuccino is the addition of milk and froth.

Espresso has only steamed water, which is passed through finely grounded coffee whereas Cappuccino has espresso with milk and froth.

A cappuccino must be served in some kind of a porcelain cup that has greater heat-retention properties. The foam on top of the cappuccino is supposed to act as an insulator and keep your cup of coffee hot for very long..

Different kinds of cappuccino:-

Cappuccino chiaro:-

It is also known as wet cappuccino and has more milk than the regular cappuccino.

Difference between Peanut butter and butter

Peanut butter and butter are two food spreads which have been used worldwide every morning in households for breakfast. Difference between peanut butter and butter are explained in their history, taste, nutritious value and effects on health. Let’s explore them in detail.

Peanut butter:-

Peanut butter is a food paste made from ground dry roasted peanuts, which is sold as either “crunchy” or “smooth” variety. Peanut butter contains hydrogenated vegetable oil to stabilize it, salt to prevent spoilage, and dextrose and other sweeteners to enhance taste.

Peanut butter marketed as Natural, or Organic, might only contain peanuts and salt.

Butter:-

Butter is a dairy product made by churning fresh or fermented cream or milk. Butter is normally produced from the milk of cow. But butter is also made from milk of other mammals like goats, sheep, buffalo and yaks. It is generally used as a spread and a condiment, as well as in cooking applications such as baking, sauce making, and frying.

Butter consists of butterfat, water and milk proteins.

History:-

Peanut butter can be traced to Marcellus Gilmore Edson, who had got a patent in 1884 for the “fluid or semi-fluid state” of the roasted peanuts when it was milled between heated surfaces.

Butter has been in use for centuries. Romans, Greeks, Indians and Arabs have been using butter for very long centuries. Most references to butter in ancient Near Eastern texts should more correctly be translated as ghee.

In India, ghee has been a symbol of purity and an offering to the gods. Since India’s prehistory, ghee has been both a staple food and used for ceremonial purposes .

The tale of the child Krishna stealing butter remains a popular children’s story in India today.

Peanut butter is solid in room temperature. Butter remains solid when refrigerated but spreads at room temperature and melts at 32 to 35 degree Celsius.

Variant:-

Peanut butter comes in two form smooth and crunchy.

Butter comes in following form:

1) Cultured butter.

2) Sweet cream butter

3) Raw cream butter.

4) Spreadable butters

5) Whipped butter

Nutrition:-

Difference between peanutbutter and butter can be seen here very clearly,as both are very different in nutritious value.Butter comes with energy of 720 kcal, it is just 590 kcal in peanut butter.

Butter has higher fat content when compared to peanut butter.Butter contain 81 gm of fat per 100 gm whereas Butter contain only 50 gm of fat per 100 gm.

Comparing the protein level, butter comes with just one gm of protein while peanut butter has 25 gm of protein content.

Difference between Peanut butter and butter(Peanut butter vs butter):-

1) Peanut Butter is made from roasted butter whereas butter is made from milk.

2) Peanut Butter is solid in room temperature whereas butter spreads at room temperature.

3) Peanut Butter has a less of calories(590 Kcal) and fat(50 gm) as compare to butter which has cal(720 Kcal) and fat (81gm).

4) Peanut butter has good amount of protein(25 gm) as compared to butter(1 gm).

5) Peanut butter is mainly used a spread whereas butter is also used as alternative to oil in cooking.

Difference between college and university

admin — Sat, 05 Dec 2009 11:07:00 +0000

Difference between college and university lies in the governance and functioning,college and university both are related to education but their function and role are different.Lets discuss about them in detail.

College:-
The institution which teaches many courses and subjects to students. These are the institution which are responsible of education to their fellow(student).They regulate all the important task to regulate all the educational activities.

University:-
University are the regulatory which can look after the colleges which are under the University as well as plan for the course offering and all other regulating activity. University offer degrees to the student who are in the affiliated colleges.

The difference between a college and a university is that generally a college offers set of degrees in one specific area whereas a university has a collection of colleges.
For instance when someone goes to a university he/she will graduate from one of their colleges such as Business College or Engineering College. Most of the time, universities are well known and they are larger than colleges.

The difference between both college and university varies a little throughout the world.

In India-A university can grant degrees, whereas colleges can only grant certificates or diplomas, not degree. Universities are considered to be more prestigious and more expensive. They offer higher courses after Bachelor’s Degree like Master’s Degrees, Doctorate Degree, and Post Doctorate Degree. Colleges are small and more focused to students. Colleges are affiliated to a University.
There is one more term in India is Deemed University. These are the colleges which can by them self act as University and they can offer different courses and provide degree.
Important thing is every university should be affiliated by UGC.(University Grants Commission).
UGC got the status of statutory body of the Indian Government through an act of Parliament in November 1956. The UGC since then has been coordinating, determining and maintaining standards of university education and teaching in the country
In USA, universities are larger and have many colleges within them.

In UK- a university can provides degree, colleges usually depends on a fully-fledged university validating its degrees. Sometimes colleges do not even provide degree level education at all.
Mostly, community colleges are very different from universities they cannot offer a 4 year degree such as B.A. or B.Sc. They can offer trade and technical certifications and training.

Australia- universities and colleges in Australia are similar to India. Universities offer degrees, but Colleges only offer Diplomas and Certificates

Difference between a college and a university (College vs university):-
1)University are big educational bodies where as colleges are institutions.
2)Universities offer many degree and courses , where as colleges offer courses of the university which they are affiliated.
3)University takes care of courses and offering , colleges takes care of educational activities.
