What is the dominant intermolecular force or bond that must be overcome in converting liquid $\mathrm{CH}_3 \mathrm{OH}$ to a gas ?
Hydrogen bonding
Dipole-dipole interaction
Covalent bonds
London dispersion force
Solution
Key Idea When $\mathrm{H}$ atom is directly linked with $\mathrm{N}$ or $\mathrm{O}$, or $\mathrm{F}$, inter or interamolecular $\mathrm{H}$-bonding is formed.
In between $\mathrm{CH}_3 \mathrm{OH}$ molecules intermolecular H-bonding exist.
Hence, it is the intermolecular H-bonding that must be overcome in converting liquid $\mathrm{CH}_3 \mathrm{OH}$ to gas.
Hence, it is the intermolecular H-bonding that must be overcome in converting liquid $\mathrm{CH}_3 \mathrm{OH}$ to gas.
