How many distinct alkene products results when 1-bromo-1-ethylcyclopentane is treated with NaOCH₃? A) 1 B) 2 C) 3 D) 4

Question

Quizplus · Accepted Answer

Treatment of 1-bromo-1-ethylcyclopentane with NaOCH₃ would result in elimination of HBr to form one or more alkene products. Since there are two β-carbons available for elimination, two different alkene products can be formed: 1-ethylcyclopentene and 3-ethylcyclopentene. However, these two alkene products are constitutional isomers and not stereoisomers, so they are considered distinct from one another. Therefore, the answer is B) 2.
