JEE Main Chemistry question

The decreasing order of boiling points of , , and alcohols (of the same carbon number) is

(A)Correct
(B)
(C)
(D)None of these

Answer: (A)

Solution

Among isomeric alcohols, increasing branching at (or near) the hydroxyl carbon reduces the molecule's surface area and packing efficiency, weakening the net van der Waals and hydrogen-bonding interactions
