Which of the following has dipole-induced dipole interaction as inter molecular force?

1. $\mathrm{NH}_3+\mathrm{C}_6 \mathrm{H}_6$
2. $\mathrm{NaCl}+\mathrm{H}_2 \mathrm{O}$
3. $\mathrm{CH}_4+\mathrm{C}_2 \mathrm{H}_6$
4. $\mathrm{HF}+\mathrm{H}_2 \mathrm{O}$

Solution

Ammonia $\left(\mathrm{NH}_3\right)$ is polar having permanent dipole moment and it induces a dipole in non-polar benzene having zero dipole moment.
