Which molecule(s)exhibit hydrogen bonding?

Question

Quizplus · Accepted Answer

HF is the only molecule that exhibits hydrogen bonding. Hydrogen bonding occurs when a hydrogen atom is bonded to a highly electronegative atom, such as nitrogen, oxygen, or fluorine, and interacts with a lone pair of electrons on another electronegative atom. In HF, the hydrogen is bonded to fluorine and is able to hydrogen bond with another molecule of HF because of the lone pair of electrons on the fluorine atom. The other molecules listed do not have hydrogen bonded to nitrogen, oxygen, or fluorine, and thus do not exhibit hydrogen bonding.
