Out of the two compounds shown above, the vapour pressure of B at a particular temperature is expected to be :

Ahigher than that of (A)
Correct Answer
Blower than that of (A)
Csame as that of (A)
Dcan be higher or lower depending upon the size of the vessel

Solution

Because of intramolecular hydrogen bonding in (B), i.e., ortho nitrophenol, the vapour pressure of ortho nitrophenol is expected to be higher than $$para \,nitrophenol.$$
Therefore, the correct option is A.
