Vedclass · Answer

(D) For alkaline earth metal hydroxides,as we move down the group from $Be$ to $Ba$,the lattice enthalpy decreases much faster than the hydration enthalpy. Consequently,the solubility of these hydroxides increases down the group. Therefore,$Be(OH)_2$ is the least soluble among them and possesses the lowest value of solubility product $(K_{sp})$.
