What is structural isomerism? Draw isomers of pentane.

Explanation

Structural isomerism is a form of isomerism in which molecules with the same molecular formula have different bonding pattern and atomic organisation.
Isomers of Pentane:
n - Pentane `H-underset(H)underset(|)overset(H)overset(|)(C )-underset(H)underset(|)overset(H)overset(|)(C )-underset(H)underset(|)overset(H)overset(|)(C )-underset(H)underset(|)overset(H)overset(|)(C )-underset(H)underset(|)overset(H)overset(|)(C )-H`
iso - Pentane `H-underset(H)underset(|)overset(H)overset(|)(C )-underset(H)underset(|)overset(H)overset(|)(C )-underset(H)underset(|)overset(H)overset(|)overset(-C-)overset(|)(C )-underset(H)underset(|)overset(H)overset(|)(C )-underset(H)underset(|)overset(H)overset(|)(C )-H`
Neo Pentane `H-underset(H)underset(|)overset(H)overset(|)(C )-underset(H)underset(|)underset(H-C-H)underset(|)overset(H)overset(|)overset(-C-)overset(|)(C )-underset(H)underset(|)overset(H)overset(|)(C )-underset(H)underset(|)overset(H)overset(|)(C )-H`
