Isomerism In Coordination Compounds

(i) isomers contain double bonded carbon atoms.
(ii) Presence of asymmetric carbon atoms, enantiomorphs and ability to rotate plane polarised light are associated with optical isomers.

(i) Enantiomers are non superimposable mirror images of each other.
(ii) Diastereomers can't be related as non super imposable mirror images of each other.
(iii) Geometrical isomers have atleast one
(iv) Structural isomers have same molecular formula but different structures,

They are not related as super imposable mirror images of each other. They are diastereomers.
