Question 48

Introduction to Organic Chemistry

Which of the following compounds has the highest boiling point?

  1. A.CH3CH2CH2CH2OH
  2. B.CH3CH2CH2CHO
  3. C.CH3CH2CH2CH3
  4. D.CH3CH2OCH2CH3.
Show the answer and explanation

Answer: A (CH3CH2CH2CH2OH)

Explanation

Butan-1-ol molecules form hydrogen bonds with each other through their –OH groups, so it boils much higher than the aldehyde, alkane or ether of similar size.
