Quizplus · Accepted Answer

Hydrogen bonding occurs when there is a hydrogen atom attached to a highly electronegative atom (N, O, or F) and there is a lone pair on another electronegative atom to accept the hydrogen bond. II (CH3OH) has an -OH group, and III (NH3) has an -NH group, both of which can participate in hydrogen bonding. I (HBr) does not have hydrogen attached to N, O, or F, so it cannot hydrogen bond.
