Vedclass · Answer

(B) An allylic alcohol is one where the $-OH$ group is attached to a carbon atom adjacent to a carbon-carbon double bond. For an allylic alcohol to be secondary,the carbon atom bearing the $-OH$ group must be attached to two other carbon atoms. In $CH_2=CH-CH(OH)-CH_3$ (but$-3-$en$-2-$ol),the $-OH$ group is on the $C-2$ carbon,which is adjacent to the double bond $(C-3=C-4)$ and is attached to two other carbon atoms ($C-1$ and $C-3$). Thus,but$-3-$en$-2-$ol is an allylic secondary alcohol.
