Question

Quizplus · Accepted Answer

The compound has a double bond between C2 and C3, and a bromine atom on C4. To name this compound using E-Z nomenclature, we first prioritize the substituents on each side of the double bond. The higher priority substituent on one side is the methyl group (C3), and the higher priority substituent on the other side is the bromine (C4). Since the priority is opposite on each side, we use the E/Z system. The bromine and methyl groups are on opposite sides of the double bond, so this is an E isomer. Since the methyl group has a higher priority than the hydrogen on C2, this is (R,E)-4-bromo-3-methylpent-2-ene.
