Vedclass · Answer

(C) The boiling point of a substance depends on the intermolecular forces present. In $NH_3$,the nitrogen atom is highly electronegative and small,which allows it to form intermolecular hydrogen bonds. In $PH_3$,the phosphorus atom is less electronegative and larger,so it does not form hydrogen bonds. Therefore,$NH_3$ has stronger intermolecular forces compared to $PH_3$,resulting in a higher boiling point.

The boiling point of $NH_3$ is higher than that of $PH_3$ because ...
