1. Ionisation isomerism
2. Linkage isomerism
3. Geometrical isomerism
4. Optical isomerism
1. Ionisation isomerism
2. Linkage isomerism
3. Geometrical isomerism
4. Optical isomerism
Options
A.1, 2, 3 and 4 are correct
B.1, 3 and 4 are correct only
C.1 and 2 are correct only
D.2, 3 and 4 are correct only
Solution
NO2- is an ambidentate ligand and can link to central metal ion either through N or O. Hence it show linkage isomerism.
There is exchange of NO2- and SO42- occurs between coordination sphere and ionization sphere. Hence it shows ionisation isomerism.
Ma5b has only one form, therefore, it does not show geometrical isomerism.
Ma5b has mirror plane, therefore, it does not show optical isomerism.
