Q. The correct order of energy of absorption for the following metal complexes is
$A :\left[ Ni ( en )_3\right]^{2+}$,
$ B :\left[ Ni \left( NH _3\right)_6\right]^{2+}$,
$C :\left[ Ni \left( H _2 O \right)_6\right]^{2+}$

Solution:

Stronger the ligand, larger the splitting & higher the energy of absorption.
$\underset{(A)}{[Ni(en)_3]^{+2}} > \underset{(B)}{[Ni(NH_3)_6]^{+2}} > \underset{(C)}{[Ni(H_2O)_6]^{+2}}$
