Which of the following facts about the complex $$[{C}{r}({N}{H}_3)_{6}]{C}l_{3}$$ is wrong?

AThe complex involves $${d}^{2}{s}{p}^{3}$$ hybridisation and is octahedral in shape.
BThe complex is paramagnetic.
CThe complex is an outer orbital complex.
Correct Answer
DThe complex gives white precipitate with silver nitrate solution.

Solution

The complex $$[Cr(NH_3)-6] Cl_3$$ involved $$d^2sp^3$$ hybridization as it involves $$(n-1)d$$ orbitals for hybridization. It is an inner orbital complex.

The d-orbital involved in hybridization belongs to the penultimate shell due to the presence of strong ligand.
