Preparation of Phenols Last Updated : 16 Feb, 2022 Comments Improve Suggest changes Like Article Like Report Alcohols and phenols are formed when a hydrogen atom in an aliphatic or aromatic hydrocarbon is replaced by a –OH group. These classes of compounds have a wide range of applications in industry as well as in everyday life. Sugar, the cotton used in fabrics, and writing paper are all composed of compounds containing –OH groups. Consider life without paper: no notebooks, books, newspapers, currency notes, cheques, certificates, and so on. Magazines with beautiful photographs and interesting stories would vanish from our lives. Alcohol contains one or more hydroxyl (OH) groups directly attached to an aliphatic hydrocarbon atom (CH3OH), whereas a phenol contains –OH group which is directly attached to an aromatic hydrocarbon atom (C6H5OH). Examples are Alcohols: CH3 – OH - Methyl alcoholCH3 – CH(OH) – CH3 - Isopropyl alcohol Phenol: C6H5-OH - Phenol Ether: CH3OCH3 - Dimethyl etherC2H5OC2H5 - Diethyl etherPreparation of Phenols Phenol is now commercially produced synthetically. In the lab, phenols are synthesized from benzene derivatives using one of the following methods: From haloarenes At 623K and 320-atmosphere pressure, chlorobenzene is fused with NaOH. The acidification of the resulting sodium phenoxide yields phenol. From benzene sulphonic acid When benzene is sulphonated with oleum, the resulting benzene sulphonic acid is heated with molten sodium hydroxide and converted to sodium phenoxide. Phenol is produced by acidifying sodium salt. From diazonium salts At 273-278 K, an aromatic primary amine is treated with nitrous acid (NaNO2 + HCl) to form a diazonium salt. Diazonium salts are hydrolyzed to phenols by heating them in water or treating them with dilute acids. From cumene Cumene, a hydrocarbon, is used to make phenol. In the presence of air, cumene (isopropyl benzene) is oxidized to cumene hydroperoxide. It is converted to phenol and acetone after being treated with dilute acid. This method also produces a significant amount of acetone as a byproduct of the reaction. Solved Questions Question 1: Write the structure of the following compounds- 2,6-Dimethylphenolortho-CresolCatechol Answer: Question 2: Write IUPAC name of the following compounds- Answer: 2 – Methylbutan – 2 – ol1 – Phenylpropan – 2 – ol1 – Ethoxypropane Question 3: Which is more acidic ethanol (CH3-CH2-OH) or phenol (C6H5-OH)? Answer: Phenol (C6H5-OH) is more acidic than ethanol (CH3-CH2-OH) because when phenol loses H+ ion, phenoxide ion is formed, which is more stable due to negative charge delocalization. Question 4: Give one reaction that shows the acidic nature of phenol? Answer: When phenol reacts with sodium hydroxide, sodium phenoxide and water are produced as products which show acidic nature of phenol. Question 5: Give chemical reaction of phenol when it is treated with dilute HNO3?
