n-Pentane has a higher boiling point than isopentane due to an increased surface-to-surface interaction of dispersion forces.

Question

Quizplus · Accepted Answer

This statement is true. n-Pentane has a linear structure, which allows for greater surface area and thus increased dispersion forces between molecules compared to the branched structure of isopentane. These stronger intermolecular forces lead to a higher boiling point for n-Pentane.
