Geometrical isomerism

What is geometrical isomerism?

Geometrical isomerism is a type of stereoisomerism where compounds differ in the arrangement of groups around a double bond or a ring structure.

How does geometrical isomerism occur in cyclic compounds?

In cyclic compounds, geometrical isomerism occurs due to the restricted rotation of the cyclic structure, leading to different spatial arrangements of substituents.

What are the two types of geometrical isomers in cyclic compounds?

The two types of geometrical isomers are cis isomers, where similar groups are on the same side, and trans isomers, where they are on opposite sides.

Can you give an example of a cyclic compound exhibiting geometrical isomerism?

An example is cyclohexene, which can exist as cis-cyclohexene and trans-cyclohexene.
