What are isomers

What are isomers? 

Answer: Compounds with identical molecular formula but different structures are called structural isomers. Organic compounds show a great level of

isomerism. 

Isomers may be structural (due to

difference in arrangement of C atoms forming chain) or stereo (due to arrangement of bonds in chain).

With increase in number of carbon atoms in a molecular formula leads to increase in number of isomers.
