NEET Chemistry Isomerism in Complexes MCQ Question
Type: MCQ-diagram based-Hard-Class 12
Consider an octahedral complex [Co(NH3)3(NO2)3]. If the three NO2 groups are arranged such that they occupy adjacent positions at the corners of an octahedral face, which type of isomer is formed?
A
Facial (fac) isomer
B
Meridional (mer) isomer
C
Linkage isomer
D
Optical isomer
Correct Answer
Option A
Detailed Explanation
In an octahedral complex like [Co(NH3)3(NO2)3], when identical ligands occupy adjacent positions at the corners of an octahedral face, it is called a facial (fac) isomer.
