After studying this Unit, you will beable to name alcohols, phenols andethers according to the IUPAC system of nomenclature; discuss the reactions involved inthe preparation of alcohols from(i) alkenes (ii) aldehydes, ketonesand carboxylic acids; discuss the reactions involved inthe preparation of phenols from(i) haloarenes (ii) benzenesulphonic acids (iii) diazoniumsalts and (iv) cumene; discuss the reactions forpreparation of ethers from(i) alcohols and (ii) alkyl halidesand sodium alkoxides/aryloxides; correlate physical properties ofalcohols, phenols and ethers withtheir structures; discuss chemical reactions of thethree classes of compounds onthe basis of their , phenols and ethers are the basic compounds for theformation of detergents, antiseptics and fragrances, , Phenols, Phenols, Phenols, Phenols, Phenolsand Eand Eand Eand Eand EthertherthertherthersssssAlcoholsAlcoho lsAlcoholsAlcoholsAlcohols, Phenols, Phenols, Phenols, Phenols, Phenolsand Eand Eand Eand Eand EthertherthertherthersssssYou have learnt that substitution of one or morehydrogen atom(s) from a hydrocarbon by another atomor a group of atoms result in the formation of an entirelynew compound having altogether different propertiesand applications
word ‘ether’ at the end. For example, CH3OC2H5 is ethylmethyl ether. Table 11.2: Common and IUPAC Names of Some Ethers Compound Common name IUPAC name CH3OCH3 Dimethyl ether Methoxymethane C2H5OC2H5 Diethyl ether Ethoxyethane CH3OCH2CH2CH3 Methyl n-propyl ether1-Methoxypropane C6H5OCH3 Methyl phenyl etherMethoxybenzene (Anisole) …
