Q. Out of the two compounds shown below, the vapour pressure of B at a particular temperature is expected to beChemistry Question Image

Solution:

Due to intramolecular $ H- $ bonding in $o$-nitrophenol it exists as a monomer while due to intermolecular $H$-bonding in $p$-nitrophenol it exists as an associate molecule. As a result, vapour pressure of a $o$-nitrophenol is higher than that of a $p$-nitrophenol.
