The dominant intermolecular force that must be overcome to convert liquid methanol to its vapour is
covalent bonds
dipole-dipole interactions
hydrogen bonds
coordinate bonds
Solution
In methanol $\left(\mathrm{CH}_3 \mathrm{OH}\right)$, intermolecular hydrogen bonding exists. When $\mathrm{H}$-atom is directly linked with nitrogen, oxygen or fluorine, it forms inter or intramolecular H-bond. Hence, the intermolecular $\mathrm{H}$-bonding in methanol molecule must be overcome in converting liquid $\mathrm{CH}_3 \mathrm{OH}$ to vapour.
