When Phenol Is Nitrated with Dilute Nitric Acid,a Mixture of O-

Question

Examlex · Accepted Answer

The Answer is In order for efficient separation of substances (from a mixture)by steam distillation,there must be relatively large differences in volatility.The more volatile substance passes over with the steam,leaving the less volatile substance in the distillation flask.
Differences in the volatility of the o- and p- nitrophenols may be predicted by considering hydrogen bonding effects: o-nitrophenol can exhibit intramolecular hydrogen bonding,while p-nitrophenol can exhibit intermolecular hydrogen bonding.Consequently,o-nitrophenol is likely to be significantly more volatile than p-nitrophenol,leading to the possibility of efficient separation by steam distillation.
By contrast,since no hydrogen bonding is possible in the products obtained by nitration of methoxybenzene,there is no predictable difference in volatility.Hence,these products cannot be separated by steam distillation.
