MHT CET Chemistry question

Boiling point of (351 K) is much higher than that of isomeric ether (248 K). This indicates

(A)hydrogen bonds are much stronger intermolecular attractions than dipole-dipole attractionsCorrect
(B)dipole-dipole attractions are much stronger than hydrogen bonds
(C) has two hydrophobic groups while has one
(D) has two hydrophilic groups while has one

Answer: (A)

Solution

Ethanol molecules are associated through intermolecular O-H...O hydrogen bonds, whereas the ether has no O-H and only weaker dipole-dipole attractions, so ethanol boils
