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

Assertion : Boiling point of p-nitrophenol is greater than that of o-nitrophenol. Reason : There is intramolecular hydrogen bonding in p-nitrophenol and intermolecular hydrogen bonding in o-nitrophenol.

Assertion : Ortho and Para dihydrogen are nuclear spin isomers. Reason : They have same nuclear spins.

Assertion: o-nitrophenol has higher boilling point than p-nitrophenol. Reason: Intermolecular hydrogen bonding is present in p-nitrophenol and intrmolecular hydrogen bonding in o-nitrophenol.

Assertion : Compounds with difference in their boiling points by about 30^(@)C can be separated by simple distillation. Reason : All liquid mixtures can be separated by distillation method.

Assertion: Boiling and melting point of amides are higher than corresponding acids Reason : It is due to strong intermolecular hydrogen bonding in their molention.

Statement I: p-Nitrophenol is a stronger acid than o-nitrophenol. Statement II: Intramolecular hydrogen bonding makes the o-isomer weaker than p-isomer.

Give reason in one or two sentences form the following: 'o-nitrophenol is steam volatile, whereas p-nitrophenol is not'.
