Vedclass · Answer

(B) The given structure is $NC-CH=CH-CN$.$1$. Identify the longest carbon chain containing the principal functional groups. The longest chain has $4$ carbon atoms.$2$. The principal functional group is the nitrile group $(-CN)$. Since there are two nitrile groups at the ends,the chain is numbered starting from one of the nitrile carbons as $1$ and $4$.$3$. The double bond is located between carbon $2$ and $3$.$4$. The parent chain is a butane derivative with a double bond,so it is a but$-2-$ene derivative.$5$. The nitrile groups are at positions $1$ and $4$,so the suffix is $1,4-$dinitrile.$6$. Combining these,the correct $IUPAC$ name is but$-2-$ene$-1,4-$dinitrile.
