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

Text Solution

Verified by Experts

`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.
