JEE Main 2003 Chemistry question

An ether is more volatile than an alcohol having the same molecular formula. This is due to

(1)alcohols having resonance structures
(2)inter-molecular hydrogen bonding in ethers
(3)inter-molecular hydrogen bonding in alcoholsCorrect
(4)dipolar character of ethers

Answer: (3)

Solution

Alcohols contain O–H groups and form intermolecular hydrogen bonds, which must be broken for vaporisation, raising their boiling points. Ethers have no O–H and cannot hydrogen-bond with each
