Cis-trans isomers do not exist for which of the following compounds, all of which have the molecular formula C₃H₄Br₂? A) 1,1-dibromopropene B) 1,2-dibromopropene C) 1,3-dibromopropene D) none of these

Question

Quizplus · Accepted Answer

Cis-trans isomers require the presence of a double bond and different substituents attached to the carbon atoms involved in the double bond. 1,1-dibromopropene cannot exhibit cis-trans isomerism because both bromine atoms are attached to the same carbon atom, leaving no room for isomerism based on different spatial arrangements around a double bond.
