Vedclass · Answer

(C) The $IUPAC$ name of the compound $CH_3-C(CH_3)=CH-COOH$ is determined by identifying the longest carbon chain containing the functional group and the double bond.$1$. The principal functional group is the carboxylic acid $(-COOH)$,which is assigned $C1$.$2$. The longest chain containing the double bond has $4$ carbon atoms,so the parent alkane is $butane$,and the acid is $butenoic \ acid$.$3$. The double bond starts at $C2$,making it $but-2-enoic \ acid$.$4$. There is a methyl group $(-CH_3)$ attached to $C3$.$5$. Combining these,the name is $3$-methyl-$2$-butenoic acid.

The $IUPAC$ name for the formula $CH_3-C(CH_3)=CH-COOH$ is:
