Vedclass · Answer

(D) Hydrolysis of metal chlorides depends on the ionic character of the $M-Cl$ bond. As we move down the group from $Be$ to $Ba$,the ionic character of the metal chloride increases due to the decrease in polarizing power of the cation. $BeCl_{2}$ is covalent and undergoes hydrolysis,whereas $BaCl_{2}$ is highly ionic and is the least susceptible to hydrolysis among the given options. Therefore,$BaCl_{2}$ is the least hydrolysed.
