Like Water, Hydrogen Fluoride, HF, and Ammonia, N

Multiple Choice

Like water, hydrogen fluoride, HF, and ammonia, N , have relatively high boiling points. Explain.

A) Even though HF and N have ionic bonds, like water they have a strong attraction for themselves.
B) Since these are all relatively small molecules, they can compact more tightly together, and will require more energy to be separated from each other.
C) The polar molecules of each of these materials have relatively strong attractions for themselves, which translates to relatively high boiling points.
D) Since these molecules interact with each other in long chains, they have many regions of attraction and are held together relatively tightly, thus, they are harder to pull apart when boiling.
