Chapter 3 Alcohols Phenols and Ethers 15 29 Examples: Dehydration of Alcohols • Complete the following reactions: CH3 OH H2SO4 180°C OH H2SO4 180°C CH3 CH3 CH3 CH3 30 Dehydration of Alcohols to Produce Ethers • Heating alcohols (R—OH) in concentrated sulfuric acid (H2SO4) at 140°C removes a molecule of water
24 8: Reactions of Phenols: Electrophilic Aromatic Substitution Table 24 4 (a review from Chapter 12) The hydroxyl group of phenols is a strong activator and o-/p-director a Halogenation Phenols are so activated that they often react with Br 2 and Cl 2 without a catalyst b Nitration c Sulfonation OH OH NO 2 + H HNO 3 NO 2 CH 3CO 2H + H
22 8: Reactions of Phenols: Electrophilic Aromatic Substitution (Table 22 3 p 922; a review from Chapter 12) The hydroxyl group of phenols is a strong activator and o-/p-director a Halogenation Phenols are so highly activated that they often react with Br 2 and Cl 2 without a catalyst b Nitration 3 N c Sulfonation OH OH O2 + H HNO3
The reactions shown to prepare ethanol and isopropyl alcohol industrially are examples of electrophilic addition of water to an alkene The preparation of higher molecular weight alcohols by hydration is not as important because rearrangements occur and product yields are reduced
Reactions of Alcohols Phenols and Ethers o Alcohols undergo two kinds of reactions: o Phenols do not participate in reactions where the C-OH bond is broken Those that involve the breaking of the oxygen-hydrogen bond (CO-H) Those that involve the rupture of the carbon-oxygen bond (C-OH) o Ethers are quite stable compounds
group Phenols are aromatic alcohols in which R is an aromatic ring This experiment will demonstrate some reactions of alcohols and phenols Although alkyl alcohols have an -OH group they do not ionize in water whereas phenols ionize like acids (donating a proton to water)
