Question

what is isomers with example

Answer 1

Isomers are two molecules with the same molecular formula but differ structurally. Therefore, isomers contain the same number of atoms for each element, but the atomic arrangement differs. Despite having the same molecular formula, the physical properties of each moleculemay differ, particularly if the functional groups associated with each molecule are different. 

Answer 2

Butane and isobutane have the same number of carbon,atoms and hydrogen atoms so thier molecular formulas are the same.however each one has a different structural formula which shows how the atoms are arranged.so we can say butane and isobutane are structural isomers.
