Vedclass · Answer

(C) The acidity of hydrides of group $16$ elements depends on the bond dissociation enthalpy. As we move down the group,the size of the central atom increases,which leads to a decrease in the bond dissociation enthalpy. Therefore,the $H-S$ bond is weaker than the $O-H$ bond,making it easier for $H_2S$ to release $H^+$ ions compared to $H_2O$.

Oxygen is more electronegative than sulphur,yet $H_2S$ is acidic in nature while $H_2O$ is neutral. This is because:
