Vedclass · Answer

(B) An allylic alcohol is one in which the hydroxyl group $(-OH)$ is attached to a $sp^3$ hybridized carbon atom adjacent to a carbon-carbon double bond.$A$ primary $(1^\circ)$ allylic alcohol has the $-OH$ group attached to a primary carbon atom (a carbon atom bonded to only one other carbon atom) that is adjacent to a double bond.Analyzing the options:$(A)$ $H_2C=CH-CH(CH_3)-OH$: The $-OH$ is on a secondary carbon. This is a secondary allylic alcohol.$(B)$ $H_2C=CH-CH_2OH$: The $-OH$ is on a primary carbon $(CH_2)$ adjacent to the $C=C$ bond. This is a primary allylic alcohol.$(C)$ $H_2C=CH-C(CH_3)_2-OH$: The $-OH$ is on a tertiary carbon. This is a tertiary allylic alcohol.$(D)$ $H_3C-CH=CH-CH(CH_3)-OH$: The $-OH$ is on a secondary carbon. This is a secondary allylic alcohol.Therefore,the correct option is $(B)$.
