Neither optical nor geometrical isomers can be distinguished by mass spectroscopy. Why
(ii) Select the pairs of
(a) Geometrical isomers,(b) Optical isomers
( c ) Identical structures




(III) Which one of followig will show optical activity
Identifly the type of insomerisum in (if no isomerism then indicate none

Isomerism| types of isomers|geometrical isomers|optical isomers

Given structures are (A) resonating structures (B) tautomers (C) geometrical isomers (D) optical isomers

If (A) and (C) show geometrical isomers but not optical isomers, and (A) is cis- and (C) is trans - isomer, which of the following is // are correct ?

The diamagnetic complex which has two geometrical and 4 optically active isomers is :

Compounds having the same molecular formula, same structure with different configuration are called stereoisomers and the phenomenon is called stereoisomerism. The phenomenon is broadly classified with three types called (a) geometrical isomerism (b) optical isomerism and (c) conformational isomerism. Which of the following compounds exhibit both geometrical as well as optical isomerism
