Question

What is the dominant intermolecular force or bond that must be overcome in converting liquid CH₃OH to a gas? 

(a) Dipole-dipole interaction 

(b) Covalent bonds 

(c) London dispersion force 

(d) Hydrogen bonding

Answer 1

The correct option is: (d) Hydrogen bonding

Explanation:

Methanol can undergo intermolecular association through H-bonding as the - OH group in alcohols is highly polarised.

As a result, in order to convert liquid CH₃OH to gaseous state, the strong hydrogen bonds must be broken.
