CBSE Class 11-science Answered

Which has higher boiling point o-nitro phenol or p-nitro phenol? Give reason for your answer.

answered-by-expert Expert Answer

p-nitrophenol has higher boling point than o-nitrophenol.

This is due to intermolecular hydrogen bonding i.e. p-nitrophenol molecules can associate with themselves.

o-nitrophenol does not undergo intermolecular hydrogen bonding because of chelation.
