WebChemical Compounds The effect of hydrogen bonding on boiling points. The boiling points of alcohols are much higher than those of alkanes with similar molecular weights. For example, ethanol, with a molecular weight (MW) of 46, has a boiling point of 78 C (173 F), while propane (MW 44) has a boiling point of -42 C (-44 F). Such a large difference in … Web1. jan 2024 · Phenols contain a hydroxyl moiety attached to an aromatic hydrocarbon group. Alcohols have broad OH stretching and bending peaks that result from hydrogen bonding. The OH stretch falls at 3350 ± 50, the OH in-plane bend falls at 1350 ± 50, and the O-H wag falls at 650 ± 50.
