NEET Chemistry Isomerism in Complexes MCQ Question
For the complex [Co(NH3)3(NO2)3], which type of isomerism can be exhibited and what would be the fac isomer's geometry?
Geometrical isomerism; adjacent ligands form an octahedral face
Linkage isomerism; different binding sites for NO2
Optical isomerism; mirror images
Coordination isomerism; interchange of ligands between metal ions
Correct Answer
Detailed Explanation
The complex [Co(NH3)3(NO2)3] can exhibit geometrical isomerism, where three ligands can occupy adjacent positions at the corners of an octahedral face, forming the fac isomer.
