We’re being asked to name the given structure using IUPAC nomenclature with the correct E/Z designation.
Recall that the E/Z designation gives us the absolute stereochemistry of double bonds. It involves:
1. Determining the highest priority groups on each side of a double bond.
• Priority is determined using atomic mass
• If the same atom is present, we compare the other atoms it is bonded to
2. Designating E/Z based on their relative position:
• If they are on the same side → Z (zusammen or together)
• If they are on the opposite side → E (entgegen or opposite)
For this problem, we need to do the following steps:
Step 1: Determine the longest carbon chain and the parent name.
Step 2: List down the substituents present and their locants.
Step 3: Determine the E/Z designation of the double bond.
Select the correct name for the following compound, including the correct (E) or (Z) designation where appropriate.
