Chemistry-Isomerism in Complexes
NEET Chemistry Isomerism in Complexes MCQ Question
Type: MCQ-numerical-Hard-Class 12
In octahedral coordination entities of the type [Co(NH3)3(NO2)3], if the three NO2 ligands occupy adjacent positions at the corners of an octahedral face, what type of isomer is formed?
A
Facial isomer
B
Meridional isomer
C
Linkage isomer
D
Optical isomer
Correct Answer
Option A
Detailed Explanation
In octahedral complexes like [Co(NH3)3(NO2)3], when three identical ligands occupy adjacent positions at the corners of an octahedral face, it results in a facial (fac) isomer. This is a form of geometrical isomerism as per the NCERT context.
