Which of the following has highest thermal stability and maximum acid strength 2

A

`H_2S`

B

`H_2O`

C

`H_2Se`

D

`H_2Te`

Text Solution

Verified by Experts

The correct Answer is:
A
Thermal stability decreases in the order `H_2O gt H_2S gt H_2Se gt H_2Te`
However, `H_2O` is neutral and `H_2S` is distinctly acidic. Thus, highest thermal stability and maximum acid strength is in case of `H_2S`
