NEET Chemistry Isomerism in Complexes Assertion Reason Question
Assertion (A): In octahedral complexes of the type [Ma3b3], geometrical isomerism can occur.
Reason (R): Geometrical isomerism arises because ligands can occupy positions at the corners of an octahedral face or around the meridian of the octahedron.
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 [Ma3b3] complexes arises due to different spatial arrangements of ligands, as described in the NCERT context about facial and meridional isomers.
