Answer : 2. "Methanol (CH3OH)"
Explanation :

Answer: B) Methanol (CH3OH) Explanation: Chemical Compounds with stronger intermolecular forces have higher boiling points.   The order of strengths of intermolecular forces is:  London dispersion < dipole-dipole < H-bonding   Methane (CH4) — London dispersion forces Dimethyl ether (CH3OCH3) — dipole-dipole attractions Methanol (CH3OH) — hydrogen bonding Therefore, Methanol - CH3OH with H-Bonding have highest Boiling Point among the given chemical compounds.
