Assertion : [Co(NO(2))3(NH3)3] does not ...

Assertion : `[Co(NO_(2))_3(NH_3)_3]` does not show optical isomerism.
Reason : It has a plane of symmetry.

A

If both (A) and (R) are correct and (R) is the correct explanation of (A).

B

If both (A) and (R) are correct, but (R) is not the correct explanation of (A).

C

If (A) is correct, but(R) is incorrect.

D

If both (A) and (R) are.incorrect.

Text Solution

Verified by Experts

The correct Answer is:
B
Optical isomerism is formed in octahedral complexes with 1, 2 or 3 symmetrical bidentate ligands only. Since given compound is not having any bidentate ligand, it will not show optical isomerism because it has plane of symmetry.
