\({H_2}S\) is more acidic than \({H_2}O\), due to
1 \(O\) is more electronegative than \(S\)
2 \(O - H\) bond is stronger than \(S - H\) bond
3 \(O - H\) bond is weaker than \(S - H\) bond
4 None of these
Explanation:
(b)The acidity of hydrides of \(VI\) group elements increase from top to bottom as the bond strength \(X - H\) decrease from top to bottom \({H_2}O < {H_2}S < {H_2}Se < {H_2}Te\)
