For hydrogen bonding to occur,a molecule must have a hydrogen atom bonded directly to a fluorine,oxygen,or nitrogen atom.

Question

Quizplus · Accepted Answer

This is because fluorine, oxygen, and nitrogen are more electronegative than hydrogen, resulting in a partial positive charge on the hydrogen atom and a partial negative charge on the fluorine, oxygen, or nitrogen atom. This creates a dipole-dipole interaction between the molecules, leading to hydrogen bonding.
