    Which of the following explanations accounts for o-nitro-phenol to be more volatile than p-nitrophenol?

    Each question has choices (a), (b), (c ) and (d) out of which ONLY ONR is correct. STATEMENT -1 : A mixture of o-nitrophenol and p-nitrophenol can be separated by steam distillation. STATEMENT - 2 : o-nitrophenol is steam volatile but p-nitrophenol is not though both are water soluble.

    This section contains Assertion and Reason type question. Each question has 4 choices (1), (2), (3) and (4), out of which only one is correct. Assertion (A) o-nitrophenol is less volatile than p-nitrophenol. Reason(R) There is intermolecular hydrogen bonding in o-nitrophenol and intramolecular hydrogen bonding in p-nitrophenol.

    Assertion (A) o-and p-nitrophenol can be separated by steam distillation. Reason (R ) o-Nitrophenol is steam volatile whereas p-nitrophenol is not steam volatile.

    Assertion : Orhto nitrphenol molecules are associated due to the presence of intermolecular hydrogen bonding while para-nitrophenol involves intramolecular, hydrogen bonding Reason: Ortho nitrophenol is more volatile than the para nitrophenol.
