In alkenes, there are four groups bonded to the carbons that constitute the carbon-carbon double bond. Which of the following situations produces cis-trans isomerism?

Question

Quizplus · Accepted Answer

Cis-trans isomerism occurs when the two groups bonded to each carbon atom in the double bond are different from one another. This creates a situation where the relative position of the groups can be different, leading to different isomers. Option A does not produce cis-trans isomerism because all four groups are the same and therefore cannot be in different positions relative to one another. Option C may lead to isomerism, but it is not necessarily cis-trans isomerism.
