The two optical isomers given below, namely, :

A)  enantiomers

B)  geometrical isomers

C)  diastereomers          

D)  structural isomers

Correct Answer: C

Solution :

 Key Idea: (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 \[C-C.\] (iv) Structural isomers have same molecular formula but different structures, \[\because \]They are not related as super imposable mirror images of each other. \[\therefore \]They are diastereomers.
