Which of the following is more soluble in ether ?

As the size of cation increases polarising power decreases sharing of electrons decreases and hence covalent character decreases and ionic caharacter increases BeCl2 purley covalent where as BaCl2 is purley ionic, solubility principle is " Like dissolves like→ That means covalent compoundd [BeCl2] are soluble in covalent solvents [ether]Note : Ether is non polar solvent (or) covalent solvent
