MCQ
Which of the following has a higher boiling point?
- ✓Butanol
- BButanal
- CBoth of them have similar boiling point
- DCannot say anything
✓
Answer
Correct option: 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.
