Vedclass · Answer

(C) To determine the $E$ isomer,we use the Cahn-Ingold-Prelog $(CIP)$ priority rules. The $E$ isomer occurs when the groups of higher priority are on opposite sides of the double bond.Structure $(1)$: The groups attached to the double bond are assigned priorities. The higher priority groups (labeled $a$) are on opposite sides,thus it is an $E$ isomer.Structure $(2)$: The higher priority groups are on the same side,making it a $Z$ isomer.Structure $(3)$: The higher priority groups are on the same side,making it a $Z$ isomer.Structure $(4)$: The higher priority groups (labeled $a$) are on opposite sides,thus it is an $E$ isomer.Therefore,structures $(1)$ and $(4)$ are $E$ isomers.

Among the following structures,select $E$ isomers (arrows indicate the bonds to be considered):
