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 applic
According to IUPAC system (Unit 12, Class XI), the name of an alcohol is derived from the name of the alkane from which the alcohol is derived, by substituting ‘e’ of alkane with the suffix ‘ol’. The position of substituents are indicated by numerals. For this, the longest carbon chain (parent chain) is numbered starting at the end ...
