Study Plan

1
Day 1–2

Learn the Theory

Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: 1. Alcohols: Basic Ideas, Classification and Properties, 2. Alcohols: Preparation, Commercial Forms and Important Tests, 3. Phenols: Structure, Acidity and Reactions.

2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 104 questions available for this chapter.

3
Day 4

Revise & Test

Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.

Day 7

Spaced Revision

Come back to Alcohols, Phenols and Ethers after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • Alcohols contain the functional group -OH.
  • Primary, secondary, and tertiary alcohols are classified by the carbon atom carrying -OH.
  • Hydrogen bonding explains the higher boiling points of alcohols.
  • Rectified spirit contains about 95.5% ethanol.
  • Absolute alcohol is 100% ethanol.
  • Methylated spirit is poisonous and unfit for drinking.
  • Phenols have -OH directly attached to an aromatic ring.
  • Phenols are more acidic than alcohols due to resonance stabilisation of phenoxide ion.
  • Electron-withdrawing groups increase phenol acidity; electron-donating groups decrease it.

Common Mistakes to Avoid

Williamson's synthesis works with any alkyl halide, including tertiary alkyl halides.

Phenolic ethers can be prepared by reacting sodium alkoxide with an aryl halide.

Secondary and tertiary alcohols are good choices for acid-catalysed dehydration to ethers.
