    here RA mean reducing agent and OA mean oxidising agent. here due to inert pair effect down the group oxidation state decrease so Tl, Pd, Bi exist as Tl+ , Pb+2 and Bi+3 ions. here Pd +4 is given so it is unstable and readily convert to Pb+2 by accepting 2e so Pb+4 is strong oxidising agent. In case of PbI4 , Pb+4 is SOA while I- is SRA so here redox reaction takes place so Pb+4 converted to Pb+2 and it exists as PbI2. in case of PbF4 F is weak RA so here redox reaction doesn't take place so PbF4 exist.
