question_answer

The two optical isomers given below, namely, \[(a)\]:

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\[C\text{ }=C\]. (iv) Structural isomers have same molecular formula but different structures. \[\therefore \]They are not related as super imposable mirror images of each other. \[\therefore \]They are diastereomers.
