Question : 18 of 18

Marks: +1, -0

Assertion (A) : Trans

[CrCl_2(ox)_2]^{3-}

shows optical isomerism.
Reason (R) : Optical isomerism is common in octahedral complexes involving didentate ligands.

Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A)
Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A)
Assertion (A) is true, but Reason (R) is false
Assertion (A) is false, but Reason (R) is true

Solution:

Trans

[CrCl_2(ox)_2]^{3-}

does not show optical isomerism because it has plane of symmetry.
yes, optical isomerism is common in octahedral complexes involving didentate ligands.

[M(aa)_3]

, when aa = bidendare ligand.
