Vedclass · Answer

(A) The acidic character of group-$16$ hydrides increases down the group.This is because the bond dissociation enthalpy of the $M-H$ bond decreases as the size of the central atom increases down the group.As the $M-H$ bond becomes weaker,it becomes easier to release a proton $(H^+)$.Therefore,the correct order is $H_2O Hence,the correct option is $(A)$.

The correct order of acidic character of group-$16$ hydrides is
