How many of the following statements is/are correct? A The order of splitting energy is P t C l 4 2 - > P d C l 4 2 - > N i C l 4 2 - (consider only magnitude) B [ N i ( C O ) 4 ] is diamagnatic whereas [ N i ( H 2 O ) 6 ] 2 + is paramagnetic. ( C ) [ N i ( C N ) 4 ] 2 - → d s p 2 hybridized and paramagnetic. D The magnetic moment of K 3 F e C N 6 is 3 B.M
Correct answer
4.00
Step-by-step solution
(a) Splitting energy increases down the group of transition metals complexes with same ligands. (b) Ni(CO) 4 → sp 3 Ni(H 2 O) 6 2+ → sp 3 d 2 (c) ( C ) [ N i ( C N ) 4 ] 2 - → d s p 2 (d) for K 3 Fe(CN) 6 ; M = 3
