Question

The correct order of energy of absorption for the following metal complexes is A :[ Ni ( en )3]2+, B :[ Ni ( NH 3)6]2+, C :[ Ni ( H 2 O )6]2+ (A) C < B < A (B) B < C < A (C) C < A < B (D) A < C < B

Stronger the ligand, larger the splitting higher the energy of absorption. underset(A)[Ni(en)3]+2 > underset(B)[Ni(NH3)6]+2 > underset(C)[Ni(H2O)6]+2

Q. The correct order of energy of absorption for the following metal complexes is
$A : [N i (e n)_{3}]^{2 +}$ ,
$B : [N i (N H_{3})_{6}]^{2 +}$ ,
$C : [N i (H_{2} O)_{6}]^{2 +}$

$C < B < A$

$B < C < A$

$C < A < B$

$A < C < B$

Stronger the ligand, larger the splitting & higher the energy of absorption.
$(A) [N i (e n)_{3}]^{+ 2} > (B) [N i (N H_{3})_{6}]^{+ 2} > (C) [N i (H_{2} O)_{6}]^{+ 2}$
