Question

What is isomerism?
Give some example clearly???

Answer 1

Isomerism is the phenomenon whereby certain compounds, with the same molecular formula, exist in different forms owing to their different organizations of atoms. The concept of isomerism illustrates the fundamental importance of molecular structure and shape in organic chemistry.Structural isomers are molecules with the same molecular formula, but their atoms have different arrangements or bonds.Butane and isobutane have the same number of carbon (C) atoms and hydrogen (H) atoms, so their molecular formulas are the same.

Answer 2

isomerism is the phenomenon of same molecular formula but different arrangement of carbon atoms .

eg - n - butane and iso- butane
