The strongest reducing agent amongst all the hydrides of Group `15` element is

A

`BiH_(3)`

B

`PH_(3)`

C

`NH_(3)`

D

`AsH_(3)`

Text Solution

Verified by Experts

The correct Answer is:
1
The tendency to liberate hydrogen inceases as we move from `NH_(3)` to `BIH_(3)`. This happen beacause the size of the central atom increases as we move down the group. Consequently ,its tendency to form strong covalent bond with realtively small `H` atom decreases.
Consequently , the reducing character of the hydrides (i.e ability to release hydrogen ) increases on moving down the group. Ammonia is only a mild reducing agent while `BiH_(3)` is the strongest reducing agent amongst all the hyderides.

    Why is BiH_(3) the strongest reducing agent amongst all the hydrides of group 15 elements ?

    Give reasons for the following: (i) Oxygen is a gas but sulphur is a solid. (ii) O_(3) acts as a powerful oxidising agent. (iii) BiH_(3) is the strongest reducing agent amongst all the hydrides of Groups 15 elements.
