Question

Quizplus · Accepted Answer

The parent chain is a 5-carbon chain with a double bond, which is pentene. There is a bromine atom on the second carbon of the double bond, making it 2-bromopentene. The carboxylic acid functional group is on the third carbon of the pentene chain, so it is 3-pentenoic acid. According to the Cahn-Ingold-Prelog priority sequence, the highest priority goes to the carboxylic acid group, so the double bond will be assigned the lowest priority. The remaining two substituents on the double bond are a hydrogen and a bromine, and they are on opposite sides of the double bond, making it a Z isomer. Therefore, the correct IUPAC name is (Z,R)-2-bromo-3-pentenoic acid.
