Quizplus · Accepted Answer

Hydrogen bonds form when a hydrogen atom in a molecule is attracted to an electronegative atom such as oxygen, nitrogen, or fluorine in another molecule. Out of the given choices, only NH₃ (ammonia) has a hydrogen atom that can form hydrogen bonds with the lone pair of electrons on the nitrogen atom. The other molecules either lack an electronegative atom or do not have a hydrogen atom bonded to an electronegative atom.
