Give reason for the following:
`PH_3` is a weaker base than `NH_3`

Text Solution

Verified by Experts

Both the molecules are pyramidal in shape and contain a lone pair of electrons on P and N. Phosphorus being bigger in size, electron density is smaller and, therefore, it is a weaker base than ammonia.
