Explain why `NH_(3)`, is basic, while `BiH_(3)` , is only feebly basic?

Text Solution

Verified by Experts

The atomic size of nitrogen is less than that of bismuth. As a result, electron density of the nitrogen atom is greater than that of bismuth atom. It means that electron releasing tendency of ammonia is more than that of `BiH_(3)`. That is the reason, ammonia is more basic than `BiH_(3)` which is only feebly basic.
