Which of the following facts about the complex [Cr(NH3)6]Cl3 is wrong?
- The complex is paramagnetic.
- The complex gives white precipitate with silver nitrate solution.
- The complex is an outer orbital complex.
- The complex involves d2sp3 hybridisation and is octahedral in shape.
In case of d3 configuration, the number of unpaired electrons remains 3 whether the ligand is strong field or weak field.
The hybridisation scheme can be shown as:
Hence, the complex is inner orbital complex as it involves (n-1)d orbitals for hybridisation.
3.93 = √(n(n+2))
So, n =3 (here n is number of unpaired electrons)
The correct option is C.
