In hydrogen bonding,hydrogen nearly always pairs with:

Question

Quizplus · Accepted Answer

Hydrogen bonding occurs when hydrogen is bonded to highly electronegative elements such as oxygen, nitrogen, or fluorine. This creates a polar covalent bond, and the partially positive hydrogen attracts the partially negative lone pairs of electrons on nearby oxygen or nitrogen atoms forming a hydrogen bond. Therefore, hydrogen nearly always pairs with oxygen or nitrogen in hydrogen bonding. Choice A is incorrect because hydrogen bonding occurs between hydrogen and a highly electronegative atom, not another hydrogen atom. Choice B and D are also incorrect because carbon and sodium/chlorine are not highly electronegative enough to form hydrogen bonds.
