Among LiCl, BeCl2, BCl3 and CCl4, the covalent bond character follows the order

LiCl < BeCl2 < BCl3 < CCl4 : Covalent character orderIn the above molecules,as the magnitude of the +ve charge increases,the polarising power of cation increases,& hence sharing of electrons increases,therefore covalent character increases.Polarising power ∞covalent character
