Study Plan
Learn the Theory
Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: 1. Carbonyl Group and Basic Reactivity, 2. Important Reactions of Aldehydes and Ketones, 3. Preparation of Carboxylic Acids.
Practise
Solve the textbook exercises and extra practice questions. There are 103 questions available for this chapter.
Revise & Test
Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.
Spaced Revision
Come back to Aldehydes, Ketones and Carboxylic Acids after a week. Use flashcards for quick recall and try past exam questions on this chapter.
What to Focus On
- Aldehydes contain a terminal carbonyl group and ketones contain an internal carbonyl group.
- The carbonyl carbon is sp2 hybridised and electrophilic.
- Aldehydes are more reactive than ketones toward nucleophilic addition.
- Primary alcohols oxidise to aldehydes; secondary alcohols oxidise to ketones.
- Tollen's reagent, Fehling's solution, and Schiff's reagent help distinguish aldehydes from ketones.
- Alpha-hydrogen atoms allow halogenation and aldol condensation.
- Carboxylic acids contain the -COOH group.
- They can be prepared by oxidation, hydrolysis, carboxylation, or side-chain oxidation.
- They react with active metals, alkalis, carbonates, and bicarbonates.
Common Mistakes to Avoid
All carboxylic acids behave like ordinary carbonyl compounds and give the usual aldehyde or ketone reactions.
Formic acid is just another simple carboxylic acid and cannot behave like an aldehyde.
Any carboxylic acid can undergo HVZ halogenation.
Memory Tips
Reactivity order of carboxylic acid derivatives
Formic acid as a special carboxylic acid
HVZ reaction exception for formic acid
Kolbe's electrolysis product pattern
