1 Alcohols, Ethers and Thiols Chapter 08 Alcohols, Ethers, and Thiols CEM 240: Fall 2016 Prof. Greg Cook 2 Alcohol Nomenclature - common imple alcohols are often named using common naming (functional class) considering the alkyl group as a substituent on the functional group. C 3 methyl alcohol C 3 C 2 ethyl alcohol a primary alcohol cyclopentyl alcohol a secondary alcohol Alcohol Nomenclature IUPAC naming is best using the carbon chain as the parent and replacing the -e ending with -ol note: alcohols outrank alkyl substituents 3 C methanol cyclopentanol propan-2-ol isopropyl alcohol a secondary alcohol t-butyl alcohol a tertiary alcohol 5-methylhexan-3-ol hexane-2,4-diol phenol N 2 o-nitrophenol 3 4 Properties of Alcohol Alcohols are polar but have other reactive features µ = 1.7 D weakly basic weakly acidic 5 ydrogen Bonding At about 5 kcal/mol, -bonds are weaker than covalent bonds but stronger than many other intermolecular forces δ hydrogen bond δ + δ δ + hydrogen bond δ + δ 6
