While separating a mixture of ortho and para nitrophenols by steam distillation, name the isomer which will be steam volatile. Give reason. |
| Answer» Solution :`to` The o-NITROPHENOL shows lower boiling POINT than para nitrophenol because of intramolecular H-bonding in the former case. THUS, o-nitrophenol will be STEAM volatile. The molecules of p-nitrophenols are STRONGLY associated by intermolecular H-bonding, as a result of which it shows higher boiling point. | |
