Quizplus · Accepted Answer

The compound has a double bond between C4 and C5 with a bromine atom attached to C4. The two substituents attached to the double bond are on opposite sides, making it a Z-isomer. The alcohol functional group is on C2. The stereochemistry at the alcohol carbon is not specified, so both R and S are possible. However, the given name indicates R configuration, which corresponds to the Z-isomer in this case. Therefore, the correct IUPAC name is (Z,R)-4-bromo-4-hexen-2-ol.
