This topic extends alcohol chemistry and introduces phenol.
What you need to know
- Alcohols Oxidation, esterification, reaction with sodium and halogenation.
- Phenol Weakly acidic, reacts with NaOH but not carbonates.
- Ring reactivity Phenol reacts with bromine water to give a white precipitate.
- Tests Distinguishing alcohols and phenols with FeCl₃ and bromine water.
Common mistakes in OA2.1 Alcohols and Phenols
- Saying phenol reacts with sodium carbonate.
- Mixing up the acidity order of water, ethanol and phenol.
- Forgetting the white precipitate with bromine water.
Try three OA2.1 Alcohols and Phenols exam-style questions
1. Explain why phenol is more acidic than ethanol. (2 marks)
Show the mark scheme answer
The negative charge on the phenoxide ion is delocalised into the ring (1), stabilising it (1).
