Vedclass · Answer

(C) The acidity is directly proportional to the tendency of the hydrogen donor. It depends upon the bond dissociation enthalpy of the $H-X$ bond,where $X$ is $O, S, Se, Te$. As we move down the group,the bond dissociation energy of hydrides decreases due to an increase in bond length,which makes the release of $H^+$ ions easier. Therefore,the acidic strength increases down the group. Hence,the correct order of acidic character of the given hydrides is $H_2Te > H_2Se > H_2S > H_2O$.

The correct order of acidic character of the following is:
