Vedclass · Answer

(B) $1$. Identify the longest carbon chain containing the double bond. The chain has $5$ carbon atoms,so the parent alkane is pentane,and the alkene is pentene.$2$. Number the chain from the end that gives the double bond the lowest possible locant. Numbering from the right gives the double bond the position $2$ ($CH_3-CH=CH-CH(CH_3)_2$ numbering $1,2,3,4,5$).$3$. Identify the substituent: there is a methyl group at position $4$.$4$. Combining these,the name is $4-$methylpent$-2-$ene.
