Question

Quizplus · Accepted Answer

The reagent needed to synthesize 3-methyl-2-pentene from 2-chloro-3-methylpentane is a strong base that can perform an E2 elimination reaction. Option D provides the base needed for this type of reaction, which is sodium ethoxide (NaOCH2CH3) in ethanol (CH3CH2OH). The base will remove the leaving group (chlorine) and the adjacent proton on the beta-carbon to form the desired alkene. Options A, B, and E do not provide the necessary reagents for E2 elimination, while option C provides a different base (sodium methoxide) that can cause unwanted reactions.
