The correct order of dipole moments for molecules $\mathrm{NH}_3, \mathrm{H}_2 \mathrm{~S}, \mathrm{CH}_4$ and $\mathrm{HF}$, is:

Question

$\mathrm{CH}_4 > \mathrm{H}_2 \mathrm{S} > \mathrm{NH}_3 > \mathrm{HF}$

$\mathrm{H}_2 \mathrm{S} > \mathrm{NH}_3 > \mathrm{HF} > \mathrm{CH}_4$

$\mathrm{NH}_3>\mathrm{HF}>\mathrm{CH}_4>\mathrm{H}_2 \mathrm{S}$

$\mathrm{HF}>\mathrm{NH}_3>\mathrm{H}_2 \mathrm{~S}>\mathrm{CH}_4$
