Isomeric pentanes have different value of boiling point for example, n-pentane has highest the boiling point among it three isomers. This is due to

Correct Answer - C
With increase in number of branched chains, the molecules attains the shape of a sphere. This results in smaller area of contact and therefore weak intermolecular forces between spherical molecules, which are overcome at relatively lower temperatures.
