Question

When is geometrical isomerism possible​

Answer 1

Answer:

The most likely example of geometric isomerism you will meet at an introductory level is but-2-ene. In one case, the CH3 groups are on opposite sides of the double bond, and in the other case they are on the same side. Geometric isomers can only occur where there is restricted rotation about a bond.
