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.
