$H_2Te$

Vedclass · Answer

(A) The acidity of hydrides of group $16$ elements increases down the group. As we move from $O$ to $Te$,the bond dissociation enthalpy of $H-E$ bond decreases due to the increase in the size of the central atom. Therefore,the order of acidic strength is: $H_2O Thus,$H_2Te$ is the most acidic hydride among the given options.

Which of the following hydrides is the most acidic?
