Account for the following: NH_3 is a stronger base than PH_3.

Answer»

Solution :`NH_3` is a stronger base than `PH_3`. Due to smaller size of N than P, electron density is more on N in `NH_3` than on P in `PH_3`. Moreover, the stability of the CONJUGATE ACID DECREASES from `NH_3` to `PH_3`. THEREFORE, `NH_3` is a stronger base than `PH_3.
