Question

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.
$(C) [N i (C N)_{4}]^{2 -} \to d s p^{2}$ hybridized and paramagnetic.
$(D)$ The magnetic moment of $K_{3} [F e {(C N)}_{6}]$ is $\sqrt{3}$ B.M

(a) Splitting energy increases down the group of transition metals complexes with same ligands.

(b) $[{Ni(CO)}_{4}] \to {sp}^{3}$
${[{Ni(H}_{2} {O)}_{6}]}^{2+} \to {sp}^{3} d^{2}$

(c) $(C) [N i (C N)_{4}]^{2 -} \to d s p^{2}$

(d) for $K_{3} [{Fe(CN)}_{6}]; M = \sqrt{3}$
