Question

What are geometric isomers?

Answer 1

Geometric isomers are compounds that differ from each other in the arrangement in space of groups about a double bond or a ring.

Explanation:

Double bond geometric isomers

cis-But-2-ene and trans-but-2-ene are geometric isomers.

The isomers are different compounds with different physical properties.

The methyl groups are always on opposite sides or the same side of the double bond, and you cannot convert one isomer to the other without breaking a bond.

Ring geometric isomers

trans-1,2-Dimethylcyclopropane and cis-1,2-dimethylcyclopropane (below) are geometric isomers.

The isomers are different compounds with different physical properties.

The methyl groups are always on opposite sides or the same side of the ring, and you cannot convert one isomer to the other without breaking a bond.
