2. In liquid propanol, CH3CH2CH2OH, which intermolecular forces are present? Dispersion, hydrogen bonding and dipole-dipole forces are present.

Does 2-propanol have a dipole moment?

Take a look at 1-propanol. Now take a look at 2-propanol. They both have hydrogen bonding, dipole-dipole, and disperson forces.

What type of intermolecular forces can occur between two isopropanol molecules?

Explanation: The intermolecular forces that operates between isopropanol molecules are (i) hydrogen bonding, and (ii) dispersion forces between the alkyl residues. (i) is probably the most significant contributor, and it reduced by comparison with say, water, because there is only the one δ−O−Hδ+ dipole in isopropanol.
