Vedclass · Answer

$(A)$ The longest carbon chain contains $5$ carbon atoms with a $C=C$ bond starting at the second carbon atom, so it is a $2$-pentene derivative.The substituents are a chlorine atom $(Cl)$ at position $2$ and an iodine atom $(I)$ at position $3$.Looking at the geometry across the $C=C$ bond, the higher priority groups (based on atomic number, $Cl$ vs $CH_3$ on one side, and $I$ vs $CH_2CH_3$ on the other) are on opposite sides of the double bond, which corresponds to the $E$ configuration, often referred to as $trans$ in simple cases where similar groups are on opposite sides.Specifically, the $Cl$ and the $CH_2CH_3$ group are on opposite sides of the double bond, and the $CH_3$ and $I$ are on opposite sides. Thus, the configuration is $trans-2-chloro-3-iodo-2-pentene$.
