Question

which cation will have greater polarizing power pb2+or pb4+​

Answer 1

Answer:

The correct option would be (2) that is Pb​4+ and Br-. This happens because if you refer to the FAJAN's rule, according to which ,cation with high charge to radius ratio posses more polarising power. It means the cation with a high charge and a smaller radius is more polarising. So Pb2+ and Fe2+ are out.
