15 2: Preparation of Alcohols by Reduction of Aldehydes and Ketones - add the equivalent of H 2 across the ?-bond of the carbonyl to yield an alcohol RR' C O [H] R' H C O R H aldehyde (R or R´= H) ? 1° alcohol ketone (R and R´? H) ? 2° alcohol Catalytic hydrogenation is not typically used for the reduction of ketones or aldehydes to
ALCOHOLS: Properties & Preparation General formula: R-OH where R is alkyl or substitued alkyl Ar-OH: phenol - different properties Nomenclature 1 Common names: Name of alkyl group followed by word alcohol 2 Carbinol system: Alcohol is considered a derivative of CH3OH Name groups replacing methyl hydrogens add the suffix carbinol 3 IUPAC:
Both ethyl alcohol and isopropyl alcohol are synthesized by acid-catalyzedaddition of water to ethylene and propylene respectively CH2=CH2 3OCH3CH2OH HCH2=CHCH3 3OCH3CHCH3OHEthanol is also produced as a supplement of for auto fuels by fermentationthe carbohydrates found in grain The process gives ethanol that contains 5 waterafter distillation
7 4 1 Preparation of Alcohols Alcohols are prepared by the following methods: 1 From alkenes (i) By acid catalysed hydration: Alkenes react with water in the presence of acid as catalyst to form alcohols In case of unsymmetrical alkenes the addition reaction takes place in accordance with Markovnikov’s rule Mechanism
