The ligand that gives dark blue color with curic ion in the laboratory is

A

`NH_(3)`

B

`I^(-)`

C

`CN^(-)`

D

`S_(2)O_(3)^(2-)`

Text Solution

Verified by Experts

The correct Answer is:
D
For strong field ligands-
`CFSE=(6 xx 0.4 -1 xx 0.6) =1.8 triangle_(0)`
one unpaired electron For weak field ligands
`CFSE =(5 xx 0.4 -2 xx 0.6) =0.8 triangle_(0)` three unpaired electrons.
