Compounds Consisting of Molecules That Can Both Donate and Accept

Compounds consisting of molecules that can both donate and accept hydrogen bonds have higher boiling points than isomeric compounds that cannot donate hydrogen bonds because

A) hydrogen bonding increases molecular stability.
B) hydrogen bonding decreases molecular stability, and less-stable molecules have a greater tendency to escape from solution.
C) hydrogen bonding between molecules lowers the vapor pressure, so a higher temperature is required to increase the vapor pressure to atmospheric pressure.
D) hydrogen bonding increases water solubility.
