D

Solution

The correct option is D 3>1>2
The decreasing order of boiling points is Pentanol >Ethanol >Propane
(3>1>2)

Pentanol and ethanol have H-bonding, but molecular mass of pentanol is more than ethanol, so it has high boiling point. Propane has the least boiling point due to non-polar character and weak van der waals forces of attraction.
