Vedclass · Answer

(A) $1$. Identify the longest carbon chain containing the double bond,which is a $pentene$ chain.$2$. Number the chain to give the double bond the lowest possible position. The double bond starts at carbon $2$,so it is a $pent-2-ene$ derivative.$3$. Identify substituents: $chloro$ at position $2$ and $iodo$ at position $3$.$4$. Determine the configuration ($E/Z$ or $cis/trans$): On carbon $2$,the priority group is $Cl$ $(Z=17)$ over $CH_3$ $(Z=6)$. On carbon $3$,the priority group is $I$ $(Z=53)$ over $CH_2CH_3$ $(Z=6)$.$5$. Since the higher priority groups ($Cl$ and $I$) are on opposite sides of the double bond,the configuration is $trans$ (or $E$).$6$. Combining these,the name is $trans-2-chloro-3-iodo-2-pentene$.
