What is the reason for the large difference in the boiling points of butanal and butan-1-ol?
Answer & explanation
Correct answer: option 2
Butanol has a polar O-H bond due to which it shows intermolecular H-bonding which is not possible in the case of butanal due to the absence of a polar bond. Hence, butanal has a higher boiling point than butan-1-ol.
