Vedclass · Answer

(B) The acidity of hydrides of group $16$ elements increases from top to bottom in the periodic table.This is because the bond dissociation enthalpy of the $X-H$ bond decreases as the size of the central atom increases from $O$ to $Te$.Since the $S-H$ bond is weaker than the $O-H$ bond,$H_2S$ releases $H^+$ ions more easily than $H_2O$,making it more acidic.Therefore,the correct reason is that the $O-H$ bond is stronger than the $S-H$ bond.

$H_2S$ is more acidic than $H_2O$,due to
