Question

Quizplus · Accepted Answer

The reaction involves the dehydrohalogenation of 2-bromobutane. This reaction results in the removal of a hydrogen and a bromide atom from adjacent carbon atoms, forming a carbon-carbon double bond. The positions of these atoms on the starting material allow for formation of both cis- and trans-2-butene, but the cis isomer is favored due to the lessened steric hindrance of the substituents.
