25.3 The chemistry of phenol

Select the true statement.

• Phenols contain an aromatic ring and an -OH group

• Phenols contain an aromatic ring, a carbon side chain, and an -OH group

• Phenols contain an -OH group directly bonded to an aromatic ring

• Phenols contain an -OH group and at least one halogen

Select the true statement about phenol in water.

• Phenol is more soluble than alcohols and partially dissociates

• Phenol is less soluble than alcohols and partially dissociates

• Phenol is more soluble than alcohols and fully dissociates

• Phenol is less soluble than alcohols and fully dissociates

Select the true statement

• Phenol reacts with sodium hydroxide but not sodium carbonate

• Phenol reacts with sodium carbonate but not with sodium hydroxide

• Phenol reacts with neither sodium carbonate nor sodium carbonate

• Phenol reacts with both sodium hydroxide and sodium carbonate

Select the true statement

• Phenol reacts with both sodium hydroxide and sodium carbonate but carboxylic acids react with neither

• Both phenols and carboxylic acids react with sodium carbonate

• Carboxylic acids react with sodium hydroxide and sodium carbonate but phenols react with neither

• Both phenols and carboxylic acids react with sodium hydroxide

Select the true statement

• Phenol is less reactive than benzene because the-OH group donates electron density to the aromatic ring

• Phenol is less reactive than benzene because the -OH group removes electron density from the aromatic ring

• Phenol is more reactive than benzene because the -OH group removes electron density to the aromatic ring

• Phenol is more reactive than benzene because the -OH group donates electron density to the aromatic ring

Select the true statement

• Phenol decolourises bromine water only in the presence of a halogen carrier catalyst

• Phenol has sufficient electron density in the aromatic ring to polarise bromine molecules

• Phenol reacts with dilute nitric acid to form a mixture of 3-nitrophenol and 3,5-dinitrophenol

• Phenol reacts with concentrated nitric acid to form 2-nitrophenol and 3-nitrophenol
