Question

Quizplus · Accepted Answer

The first compound, C(CH₃)₄, has a higher vapor pressure because it has a shorter carbon-chain length and therefore less intermolecular forces holding it together. In contrast, the second compound has four longer carbon chains, which have stronger van der Waals forces and lower vapor pressure.

C(CH3)4 Has a Higher Vapor Pressure Than CH3CH2CH2CH2CH3

C(CH₃)₄ Has a Higher Vapor Pressure Than CH₃CH₂CH₂CH₂CH₃
