Vedclass · Answer

(D) According to the Cahn-Ingold-Prelog $(CIP)$ priority rules,if the groups with higher priority are on the same side of the double bond,the configuration is '$Z$' (zusammen). If they are on opposite sides,it is '$E$' (entgegen).For $(i)$: Priority at left carbon: $Cl > H$; Priority at right carbon: $Br > F$. Since $Cl$ and $Br$ are on the same side,it is $(Z)$.For $(ii)$: Priority at left carbon: $Cl > H$; Priority at right carbon: $Br > F$. Since $Cl$ and $Br$ are on opposite sides,it is $(E)$.For $(iii)$: Priority at left carbon: $Br > Cl$; Priority at right carbon: $CH_3 > H$. Since $Br$ and $CH_3$ are on the same side,it is $(Z)$.Therefore,compounds $(i)$ and $(iii)$ have $(Z)$ configuration.

Which of the following compound$(s)$ has '$Z$' configuration?
