$H_2Te$

Vedclass · Answer

(C) The acidic strength of hydrides of group $16$ elements increases down the group. As we move from $O$ to $Te$,the atomic size of the central atom increases. This leads to an increase in the bond length of the $H-E$ bond (where $E = O, S, Se, Te$). Consequently,the bond dissociation enthalpy decreases,making it easier to release $H^+$ ions. Therefore,the order of acidic strength is $H_2O Thus,$H_2Te$ is the strongest acid among the given options.
