Which of the following has the lowest boiling point?

Options

  1. ACH ₃ CH ₂ OH
  2. BCH ₃- CH ₂- NH ₂
  3. CCH ₃- O - CH ₃
  4. DHCOOH

Correct answer

C. CH ₃- O - CH ₃

Step-by-step solution

We are given alcohol, carboxylic acid, amine and ether. So, the boiling point of ether ( CH ₃- O - CH ₃ ) will be lowest in alcohol and carboxyl acid and amines, there is H-bonding responsible for higher boiling point as compared to ether.
