Question

A molecule that undergoes hydrogen bonding must:
Options
A Contain a large electronegative atom only
B Have a polar covalent bond with hydrogen and a small electronegative atom
Correct Answer
C Be a nonpolar molecule
D Be ionic in nature
Correct Answer

Option B is the correct answer.

Detailed Explanation

Hydrogen bonding requires a hydrogen atom covalently bonded to a small, highly electronegative atom (N, O, or F). This creates a strong dipole, allowing the partially positive hydrogen to be attracted to lone pairs on other electronegative atoms.

Hint

The hydrogen must be bonded to one of three specific small, electronegative atoms: Nitrogen, Oxygen, or Fluorine.
