Hydrogen bonding occurs where hydrogen is bound to a strongly electronegative element such as fluorine, or oxygen, or nitrogen. The hydrides of these elements (which we call what?) have elevated normal boiling points.

#### Explanation:

$B .$ $\text{Hydrogen bonding}$ is the dominant intermolecular force of attraction. $\text{Dipole-dipole bonding}$ is secondary. $\text{Dispersion forces}$, possessed by all molecules is the least potent intermolecular force.
