Which of the following has a higher boiling point?
Open in App
Solution
The correct option is A Butanol
There is a large difference between boiling points of butanol and butanal, although they have almost the same solubility in water. Butanol contains -OH group and can form hydrogen bonds. Hence, the molecules are associated. A large amount of energy is required to break the association. Hence, butanol has a higher boiling point. Hydrogen bonding is not possible in butanal.
