Among alkenes , alkynes and aromatic hydrocarbons , why only alkenes exhibit cis - trans isomerism has to be explained. Concept Introduction: The geometric isomers are said to be the isomers which shows different orientation of groups around a double bond. The geometric isomers are also known as cis - trans isomers. When two similar or higher priority groups are attached to the carbon on same side, it is said to be cis -isomer. When two similar or higher priority groups are attached to the carbon on opposite sides, it is said to be trans -isomer. To exhibit the geometric isomerism, a molecule should have double bonded carbon atoms ( C=C ) and each double bonded carbon should be bonded to two different groups.
