Difference Between Organic and Inorganic Compounds

Difference Between Organic and Inorganic Compounds
organic 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.

                                                         or 
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
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
prism-and-refraction-of-light-into-rainbow 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.
