NEET Chemistry Isomerism in Complexes MCQ Question
Consider an octahedral complex with the formula [Co(NH3)3(NO2)3]. Which type of isomerism is illustrated by the different spatial arrangement of the NO2 ligands in the complex?

Geometrical isomerism
Linkage isomerism
Optical isomerism
Coordination isomerism
Correct Answer
Detailed Explanation
In the complex [Co(NH3)3(NO2)3], geometrical isomerism arises when the NO2 ligands occupy different positions around the central metal ion, forming either facial or meridional isomers.
