Quizplus · Accepted Answer

Hydrogen bonding occurs when hydrogen is bonded to a highly electronegative atom such as oxygen or nitrogen. Sulfur is less electronegative than oxygen, so the hydrogen-sulfur bond in thiols is not polar enough to participate in hydrogen bonding to the same extent as the hydrogen-oxygen bond in alcohols. The solubility of thiols and their boiling points compared to alcohols have no direct impact on the extent of hydrogen bonding.
