NEET Chemistry Isomerism in Complexes Assertion Reason Question
Assertion (A): Geometrical isomerism is possible in octahedral complexes of the type [Ma3b3]. | Reason (R): In such complexes, ligands can occupy either facial or meridional positions, leading to distinct isomers.
Both (A) and (R) are true and (R) is the correct explanation of (A).
Both (A) and (R) are true but (R) is not the correct explanation of (A).
(A) is true but (R) is false.
(A) is false.
Correct Answer
Detailed Explanation
Geometrical isomerism in octahedral complexes like [Ma3b3] occurs due to different spatial arrangements of ligands, as described in the NCERT context where ligands can occupy facial or meridional positions.
