    ZnCl2 and CdCl2 have more ionic character and HgCL2 pssess covalent character

    MgCl2 < CaCl2 < SrCl2 < BaCl2. ZnCl2, CdCl2 are ionic but less than IIA, HgCl2 is covalent

    So according to fajan’s rule order of covalent character is ZnCl2 > CdCl2 > HgCl2

    with increase in size,the covalent character increases as Zeff nuclear charges incresaes
