The vapour pressure of is higher than due to

The vapour pressure of The vapour pressure of is higher than due to
is higher than The vapour pressure of is higher than due to
due to

Options

  1. ADipole moment
  2. BDipole- dipole interaction
  3. CH\mathrm{H} - bonding
  4. DLattice structure

Correct answer

C. H\mathrm{H} - bonding

Step-by-step solution

Ortho-nitrophenol has intramolecular H bonding The vapour pressure of is higher than due to
and paranitrophenol has intermolecular H-bonding. The vapour pressure of is higher than due to
Hence former is more volatile than latter.
