Coulombic Forces and Vapor Pressure

APCHEM-OK8PZI

Which of the following would have the lowest vapor pressure in the pure state?

A

Sodium hydroxide because of the strong interparticle forces of ionic solids.

B

Methanol because of the hydrogen bonding in the functional group along with the non-polar nature of the carbon-hydrogen bonds.

C

Water because of the very strong hydrogen bonding in the substance.

D

Ammonia because of the unbonded pair of electrons on the central atom coupled with hydrogen bonding in the substance.
