Which among the following compounds does not act as a reducing agent?

A

`H_(2)O`

B

`H_(2)S`

C

`H_(2)Se`

D

`H_(2)Te`

Text Solution

Verified by Experts

The correct Answer is:
A
The reducing power of hydride of 10th group element increases as `H_(2)O lt H_(2)S lt H_(2)Se lt H_(2)Te` because on moving `H_(2)O` to `H_(2)Te` size of central atom increases and hence thermal stability decreases.
