$H_2Te$

Vedclass · Answer

(D) $1$. Acidic strength of hydrides of group $16$ elements depends on the bond dissociation enthalpy of the $H-E$ bond.$2$. As we move down the group from $O$ to $Te$, the atomic size increases, which leads to an increase in the bond length and a decrease in the $H-E$ bond dissociation enthalpy.$3$. $A$ weaker $H-E$ bond is easier to break, making it easier to release $H^+$ ions.$4$. Therefore, the acidic strength increases in the order: $H_2O $5$. Thus, $H_2Te$ is the most acidic compound.
