Vedclass · Answer

(C) benzylic alcohol is one where the hydroxyl group $(-OH)$ is attached to a carbon atom that is directly bonded to a benzene ring.In a tertiary $(3^{\circ})$ alcohol,the carbon atom bearing the $-OH$ group is attached to three other carbon atoms.Let's analyze the structures:$A$: Phenyl methanol $(C_6H_5CH_2OH)$ - The carbon attached to $-OH$ is bonded to one carbon (the benzene ring),making it a primary $(1^{\circ})$ alcohol.$B$: $1$-phenyl ethanol $(C_6H_5CH(OH)CH_3)$ - The carbon attached to $-OH$ is bonded to two carbons,making it a secondary $(2^{\circ})$ alcohol.$C$: $2$-phenyl propan-$2$-ol $(C_6H_5C(CH_3)_2OH)$ - The carbon attached to $-OH$ is bonded to three carbons (two methyl groups and one phenyl group),making it a tertiary $(3^{\circ})$ alcohol.$D$: $1$-phenyl propan-$2$-ol $(C_6H_5CH_2CH(OH)CH_3)$ - This is not a benzylic alcohol because the $-OH$ is not on the carbon directly attached to the benzene ring.Therefore,the correct option is $C$.
