Which of the following facts about the complex [Cr(NH 3 ) 6 ]Cl 3 is wrong ?
Text Solution
Verified by ExpertsThe correct answer is:
C
In case of d 3 configuration, the number of unpaired electrons remains 3 whether the ligand is strong field or weak field. The hybridisation scheme can be shown as follow :
[Cr(NH 3 ) 3 ] 3+ = 
Hence the complex is inner orbital complex as it involves (n – 1) d orbitals for hybridisation,
3.93 = 
; so n = 3 (here n is number of unpaired electron(s)).
