Number of possible isomers for the complex [Co(en)2Cl2] CI will be: (en = ethylenediamine)
2
1
3
4
As we discussed in concept
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
-
&
Optical Isomerism -
Optical isomers are mirror images that cannot be suprimposed on one another
-
The complex will passes two geometrical isomer (Cis and trans) and its Cis isomer is optically active that's why the total number of isomer in is three.
