Question

The intermolecular force of attraction present between $N{H}_3$ and $C_6{H}_6$ is:

• A. Dipole-dipole interaction
• B. Dipole-induced dipole interaction
• C. London dispersion force
• D. H-bonding

Answer 1

The correct option is B Dipole-induced dipole interaction

$N{H}_3$ is a polar molecule whereas $C_6{H}_6$ is a non -polar molecule.
When the polar $N{H}_3$ molecule comes closer to the non -polar $C_6{H}_6$ molecule, it induces a dipole in the latter by disturbing the electron cloud.
Dipole-induced dipole is a weak attraction that arises when a polar molecule disturbs the electron cloud of a non-polar species.
