Chemistry - STEREO ISOMERISM Question with Solution | TestHub

Explanation Question: To select a compound which can not show geometrical isomerism.

Concept: This question is based on conditions to show geometrical isomerism.

Solution:

Condition of geometrical isomerism

(1) Restricted rotation around a double bond or ring system.

(2) Each carbon of double bond (or ring carbon) must be attached to two different groups and this two different groups must lie in same plane

(1)

(not follow condition of geometrical isomerism)

(2)

(follow condition of geometrical isomerism)

(3)

(follow condition of geometrical isomerism)

(4)

(follow condition of geometrical isomerism)
