Question

1. what type of intermolecular force is unique to alcohols and significantly impacts their boiling points?

hydrogen bonding
van der waals forces
london dispersion forces
dipole - dipole interactions

Explanation:

Hydrogen bonding is a particularly strong type of intermolecular force unique to molecules with hydrogen bonded to highly - electronegative atoms (N, O, F). It has a significant impact on boiling points as it requires more energy to break these strong intermolecular attractions. Other forces like Van der Waals (including London dispersion and dipole - dipole) are weaker in comparison.

Answer:

Hydrogen bonding
