# Q 12.3     Arrange the following compounds in increasing order of their boiling points.                $CH_{3}CHO, CH_{3}CH_{2}OH,CH_{3}OCH_{3}, CH_{3}CH_{2}CH_{3}$

Increasing order in their boiling points-

$CH_{3}CH_{2}CH_{3}

Alcohol has the highest boiling point due to more extensive intermolecular H-bonding. Aldehyde is more polar than ether so, ethanal has high BP than ethyl ether. And alkane has the lowest BP.
