The type of isomerism shown by the complex [CoCl2(en)2] is
Ionization isomerism
Coordination isomerism
Geometrical isomerism
Linkage isomerism
As we learnt that
Geometrical Isomers -
This is due to the difference in relative position of the ligands attached to the central metal atom with respect to each other
-
[CoCl2(en)2] shows geometrical Isomerism .
Option 1)
Ionization isomerism
This is incorrect.
Option 2)
Coordination isomerism
This is incorrect.
Option 3)
Geometrical isomerism
This is correct.
Option 4)
Linkage isomerism
This is incorrect.
