Vedclass · Answer

(B) To determine the $IUPAC$ name,first identify the longest carbon chain containing the double bond. The chain $CH_2 = CH - CH(CH_3) - CH_3$ has $4$ carbon atoms,so the parent alkane is butane. Numbering the chain from the end closer to the double bond gives the double bond position at $C-1$. The methyl group is attached at the $C-3$ position. Therefore,the correct name is $3-$methylbut$-1-$ene.
