Question

Rank the following substances in order of increasing boiling point (lowest → highest): (1) CH3CH2CH2CH2OH, (2) (CH3)2CHOCH3, (3) (CH3)3COH
Options
A (1) < (2) < (3)
B (2) < (1) < (3)
C (2) < (3) < (1)
Correct Answer
D (3) < (2) < (1)
Correct Answer

Option C is the correct answer.

Detailed Explanation

Increasing boiling point order: (2) (CH3)2CHOCH3 (ether, no H-bonding, lowest BP) < (3) (CH3)3COH (tertiary alcohol, branched, H-bonding but less surface area) < (1) CH3CH2CH2CH2OH (primary alcohol, straight chain, strongest H-bonding, highest BP).

Hint

How do branching and hydrogen bonding affect boiling points?
