H2S is more acidic than H2O. The reason ...

`H_2S` is more acidic than `H_2O`. The reason is

A

`O-H` bond is stronger than `S-H` bond

B

`O` is more electronegative than S

C

`H-S` bond is stronger than `O-H` bond

D

`O-H` bond is weaker than `H-S` bond

Text Solution

Verified by Experts

The correct Answer is:
A
To release `H^(+)` (proton), the `H-E` (E stands for element which may be O or S) bond must be broken. On account of relatively large size of S atom, the `H-S` bond is weaker than the `O-H` bond and, hence, easy to break.
