Question

Which of the following facts about the complex

$\lbrack Cr(NH_{3})_{6}\rbrack Cl_{3}$is wrong?

• A. The complex involves $d^{2}sp^{3}$hybridizations 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 solutions.

Answer 1

Answer: (C)

The complex is an outer orbital complex.

Answer 2

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