Take CBT

Question

Which of the following correctly orders boiling points for similar molecular weight compounds?
Options
A Hydrocarbons > Amines > Alcohols
B Alcohols > Amines > Hydrocarbons
Correct Answer
C Amines > Alcohols > Hydrocarbons
D Hydrocarbons > Alcohols > Amines
Correct Answer

Option B is the correct answer.

Detailed Explanation

Alcohols have the highest boiling points due to strong O-H hydrogen bonding, followed by amines (N-H hydrogen bonding, weaker), then hydrocarbons (only London forces).

Hint

O-H bond is more polar than N-H.
