Question

Which of the following facts about the complex $[Cr(NH_{3})_{6}]Cl_{3}$ is wrong?

• A. The complex involves $d^{2}sp^{3}$ hybridisation and is octahedral in shape
• B. The complex is paramagnetic
• C. The complex is an outer orbital complex
• D. The complex gives white precipitate with silver nitrate solution

Answer 1

Answer: (C)

The complex is an outer orbital complex

Answer 2

The complex $[Cr(NH_{3})_{6}]Cl_{3}$ involves $d^{2}sp^{3}$ hybridization as it involves $(n -1)d$ orbitals for ; hybridization. It is an inner orbital complex.
