Unlike PbCl4, PI4 and PBr4 are not found because :
A
Bromine and iodine are more electronegative than chlorine.
B
Iodine and bromine are smaller in size.
C
Larger iodine and bromine are able to reduce Pb4+ to Pb2+ or Pb.
D
The statement is incorrect.
Answer
Larger iodine and bromine are able to reduce Pb4+ to Pb2+ or Pb.
Explanation
Solution
Pb4+ has higher polarising power and Br– and I– being larger in size can easily give the electrons to Pb4+ i.e. as compared to Cl–, Br– and I– are good reducing agents.
