Explain why is `NH_(3)` basic while `"BiH"_(3)` is only feebly basic.

Text Solution

Verified by Experts

`NH_(3)` is basic while `"BiH"_(3)` is only feebly basic.
Explanation :
`to` Due to small atomic size of nitrogen, the electron density on nitrogen atom is greater than that on Bi atom. So electron releasing tendency is greater in `NH_(3)`.
Hence `NH_(3)` is basic and `"BiH"_(3)` is feebly basic.
