Q:

Which of the following chemical compounds has the highest boiling point?

A) Dimethyl ether (CH3OCH3) B) Methanol (CH3OH)
C) Methane (CH4) D) None
 
Answer & 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.
