Which of the following facls about the complex `|Cr(NH_(3))_(6)|Cl_(3)` is wrong

Options

A. The complex is paramagnetic
B. The complex is diamagnetic
C. The complex gives white precipitate with silver nitrate solution
D. The complex involves `d^(2)sp^(3)` hybridisation and is octahedral in shape.

Answer

B

Explanation

In `|Cr(NH_(3))_(6)|Cl_(3), Cr^(3+) = d^(2)sp^(3)` hybridisation number of unpaired electrons = 3 paramagnetic.
The complex is inner orbital complex as it involves (n - 1) d orbitala for hybridization
