Choose the process involved in the separation of ortho and para nitrophenol and the reason behind respectively
| A. |
steam distillation, metallic bonding |
| B. |
sublimation, Hydrogen bonding |
| C. |
steam distillation, van der Waal's forces |
| D. |
steam distillation, Hydrogen bonding |
 |
o-nitrophenol is steam volatile due to intramolecular hydrogen bonding while p-nitrophenol is less volatile due to inter molecular H-bonding hence they can be separated by steam distillation only.
