Vedclass · Answer

(B) The acidity of hydrides of group $16$ elements depends on the bond dissociation enthalpy of the $H-E$ bond.As we move down the group,the size of the central atom increases,which leads to a decrease in the $H-E$ bond dissociation enthalpy.Consequently,the ease of releasing $H^+$ ions increases,meaning the acidity increases down the group.The correct order of acidity $(K_a)$ is: $H_2Te > H_2Se > H_2S > H_2O$.

The correct order of $K_a$ in aqueous solution at $298 \ K$.
