Alcohols (part-1) Classification And Nomenclature | Chemistry 12th state board | by Vilas Academy

Summary:- Alcohols (ROH) Organic compounds containing –OH group attached to a carbon atom. 1. Classification of Alcohols A. Based on Carbon Type (–OH attached to): Primary (1°): –OH on carbon attached to 1 alkyl group Example: CH₃CH₂OH (Ethanol) Secondary (2°): –OH on carbon attached to 2 alkyl groups Example: CH₃CHOHCH₃ (Isopropanol) Tertiary (3°): –OH on carbon attached to 3 alkyl groups Example: (CH₃)₃COH B. Based on Nature of Hydrocarbon Chain: Alkanols: ROH attached to alkyl chain Aromatic alcohols (Phenols): –OH attached to benzene ring 2. Nomenclature of Alcohols (IUPAC) Method 1 – Common name: Name alkyl group + “alcohol” Example: CH₃CH₂OH → Ethyl alcohol Method 2 – IUPAC name: Select longest chain containing –OH as parent Replace –e of alkane with –ol Number chain to give –OH lowest locant Example: CH₃CH₂OH → Ethanol Example: CH₃CHOHCH₃ → 2‑Propanol #alcoholsphenolsandethers #alcoholschemistry #class12chemistry #organicchemistry #chemistrylectures #jeechemitry #neetchemistry #cetchemistry #alcoholclassification #preparationofalcohols #propertiesofalcohols #reactionsofalcohols #organicreactions #chemistryforboards #stateboardclass12 #hscclass12 #chemistrymadeeasy #studywithmechemistry
