Which of the following statements is correct for complex `[Cr(NH_(3))(CN)_(4)(NO)]^(2-)`(given that n=1)?

A

It is `d^(2)sp^(3)` hybridised.

B

The chromium is in +1 oxidation state

C

It is heteroleptic complex and its aqueous solution is coloured

D

All of these

Text Solution

Verified by Experts

The correct Answer is:
D

Central metal ion has one unpaired electron and thus d-d transition of electron is possible. This atrrbute to the colour of the solution. As different types of ligands are attached to central metal ion, the complex is called heteroleptic complex.
