Vedclass · Answer

(A) The given structure is $CH_2=CH-CH(OH)-CH_3$.$1$. Identify the longest carbon chain containing the principal functional group $(-OH)$ and the double bond. The chain has $4$ carbon atoms,so the parent alkane is butane.$2$. Number the chain from the end that gives the lowest possible locant to the principal functional group $(-OH)$.$3$. Numbering from right to left: $C_1$ is $CH_3$,$C_2$ is $CH(OH)$,$C_3$ is $CH$,$C_4$ is $CH_2$. The $-OH$ group is at position $2$ and the double bond is at position $3$.$4$. The name is constructed as: (alkene part) + (alcohol part) = But-$3$-en-$2$-ol.

The correct $IUPAC$ name of the following compound is:
