Which of the following statements best explains the observation that hydrogen fluoride has the highest boiling point of all the
olasank [31]

Answer:

c. HF can participate in hydrogen bonding.

Explanation:

<u>The boiling points of substances  often reflect the strength of the </u><u>intermolecular forces</u><u> operating among the molecules.</u>

If it takes more energy to  separate molecules of HF than of the rest of the hydrogen halides because HF molecules are held  together by stronger intermolecular forces, then the boiling point of HF will be higher than  that of all the hydrogen halides.

A particularly strong  type of intermolecular attraction is called the hydrogen bond, <em>which is a special type of dipole-dipole interaction between the hydrogen atom in a polar bond</em>, such as N-H, O-H, or F-H, and an electronegative O, N, or F atom.
