JEE Main Chemistry question

The correct order of boiling point for primary (1°), secondary (2°) and tertiary (3°) alcohols is **[MHT-CET 2008]**

(A)1° > 2° > 3°Correct
(B)3° > 2° > 1°
(C)2° > 1° > 3°
(D)2° > 3° > 1°

Answer: (A)

Solution

Isomeric alcohols of the same molecular formula have nearly the same molar mass, so boiling point is governed mainly by surface area and extent of hydrogen bonding, both of which are greatest for the
