Question

Which of following complex will not show colour?
a) [Cr(NH₃)₆]Cl₃
b) K₃[VF₆]
c) [Sc(H₂O)₆]³⁺
d) [NiCl₄]²⁻

Answer 1

option c is the correct answer

Answer 2

c) [Sc(H₂O)₆]³⁺

Low-lying electronically excited states of the [Fe(H2O)6](2+) as well as [Fe(H2O)6](3+) clusters with the multi configuration electronic structure theory.

The potential energy curves (PECs) with respect to the iron-oxygen distance so it removes all water ligands from the cluster minima.

It mainly establishes their correlation with long-range dissociation channels with most of the high end option.
