Question: is pbcl2 ionic or covalent?
Answer: PbCl2 is an ionic compound. According to Fajans' rule, greater the charge on the cation, more is its ability to polarize the bonding electrons towards itself. The charge on Pb in PbCl2 is +2 and that on PbCl4 is +4 and therefore, Pb is not able to polarize the bonding electrons in PbCl2. Hence, PbCl2 is ionic.
