Text Solution

Verified by Experts

While separating a mixture of ortho and para nitrophenols by steam distillation , ortho nitrophenol is steam volatile.
Reason: In ortho nitrophenol intra molecular hydrogen bonding is present and in case of para nitrophenol inter molecular hydrogen bonding is present . So O-nitrophenol is steam volatile.
