Vedclass · Answer

(A) $1$. Identify the longest carbon chain containing the double bond. The longest chain has $6$ carbons,so the parent alkane is hexane,and with the double bond,it is hexene.$2$. Number the chain from the end that gives the double bond the lowest possible locant. Numbering from left to right,the double bond starts at carbon $2$.$3$. Identify the substituent: At position $3$,there is a propyl group $(-CH_2CH_2CH_3)$.$4$. Combining these,the name is $3-$propylhex$-2-$ene.

Column $I$ (Structure)	Column $II$ ($IUPAC$ Name)
