Which of the following structures is classified correctly as a secondary allylic alcohol? — Alcohols Phenols and Ethers Chemistry Question

💡 Solution & Explanation

An allylic alcohol features an $-OH$ group attached to an $sp^3$ hybridized carbon adjacent to a $C=C$ double bond. In $CH_2=CH-CH(CH_3)OH$, the $sp^3$ carbon is attached to one vinyl group, one methyl group, and one hydrogen, making it secondary ($2^\circ$).
