While separating a mixture of ortho and para nitrophenols by steam distillation, name the isomer which will be steam volatile? Give reason.

Q. Assertion :While separating a mixture of ortho- and paranitrophenols by steam distillation, name the isomer which will be steam volatile. Reason: o-nitrophenol is steam volatile due to chelation (intramolecular H-bonding) and hence can be separated by stream distillation from p-nitrophenol, which is not steam volatile because of intermolecular H-bonding.

Q. What is the action of the nitrating mixture on phenol?
While separating O- and P- nitrophenol by steam distillation, Name the isomer which is steam volatile. Give reason.

Q. Assertion :A mixture of o-nitrophenol and p-nitrophenol can be separated by steam distillation. Reason: p-nitrophenol is steam volatile whereas o-nitrophenol is not steam volatile.

Q. Why ortho-Nitrophenol is steam volatile while para-Nitrophenol is less volatile?

Q. Assertion (A) : Ortho and para nitrophenols can be separated by steam distillation.
Reason (R) : Ortho nitrophenol exhibits intramolecular hydrogen bonding while para nitrophenol exists as associated molecules.
