Why H2S is more acidic than H2O ?

Question

Why H2S is more acidic than H2O ? (A) O-H bond is stronger than S-H bond (B) O-H bond is weaker than S-H bond (C) O is more electronegative than S (D) None of these

Tardigrade Admin · Accepted Answer

The acidity of hydrides of VI group elements increase from top to bottom as the bond strength X-H decrease from top to bottom H2O < H2S < H2Se < H2Te

Q. Why $H_{2} S$ is more acidic than $H_{2} O$ ?

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

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

$O$ is more electronegative than $S$

None of these

The acidity of hydrides of $V I$ group elements increase from top to bottom as the bond strength $X - H$ decrease from top to bottom

$H_{2} O < H_{2} S < H_{2} S e < H_{2} T e$

Q. Why H2​S is more acidic than H2​O ?

O−H bond is stronger than S−H bond

O−H bond is weaker than S−H bond

O is more electronegative than S
