Vedclass · Answer

(B) $1$. Identify the principal functional group or the parent chain. Here,the cyclic ring (cyclohexadiene) is the parent chain.$2$. Number the ring starting from the carbon attached to the ethenyl group as $1$,or such that the double bonds get the lowest possible locants.$3$. If we start numbering from the carbon attached to the ethenyl group as $1$,the double bonds are at positions $2$ and $4$. This gives the name $1-$ethenylcyclohexa$-2,4-$diene.$4$. However,according to $IUPAC$ rules for numbering,we should give the lowest locants to the double bonds. If we number the ring such that the double bonds are at $1$ and $3$,the ethenyl group will be at position $5$. This gives the name $5-$ethenylcyclohexa$-1,3-$diene.$5$. Comparing the locant sets: $(1, 2, 4)$ vs $(1, 3, 5)$. The set $(1, 3, 5)$ is preferred as it provides lower locants for the double bonds.$6$. Therefore,the correct $IUPAC$ name is $5-$ethenylcyclohexa$-1,3-$diene.
