Question

List-I contains complexes and their behaviour is mentioned in List-II.

LIST I	LIST II
(P) $[C u (CN)_{4}]^{3 -}$	(1) Colourless complex
(Q) $[FeF_{6}]^{3 -}$	(2) Back donation from metal to ligand takes place
(R) $[Cr (en)_{3}]^{3 +}$	(3) Coordination number is six
(S) $[Ni (CO)_{4}]$	(4) Square planar complex
	(5) Chelate complex
