Question

Liquid pentanol contains polar -OH functional groups, which can form hydrogen bonds with each other. This means that hydrogen bonding forces are present. Additionally, the molecule has a polar overall shape due to the asymmetry of the -OH groups, resulting in dipole-dipole forces. Finally, all molecules have dispersion forces present, and these are particularly strong in carbon-based molecules such as pentanol due to the large number of electrons in the atoms. Therefore, dispersion, hydrogen bonding, and dipole-dipole forces are all present in liquid pentanol. Option A is the only choice that includes all three of these forces.
