Question

(e) Which of the following should have
higher boiling point? Explain briefly.
1,5-pentanediol or 1-pentanol
​

Answer 1

Generally alcohols have higher boiling point due to hydrogen bonding.

1 pentanol is mono alcoholic whereas 1,5 pentanol is di alcoholic, therefore there will be extensive hydrogen bonding in 1,5 pentanol as compared to 1 pentanol.

Hence 1,5 pentanol has higher boiling point than 1 pentanol.
