Aldehydes, Ketones and Carboxylic Acids: Class 12 Chemistry (UP Board) important questions and practice
Aldehydes, Ketones and Carboxylic Acids is chapter 8 of 10 in UP Board Class 12 Chemistry. Below are the topics the paper draws from, the question types that come up again and again, and a free practice test on this chapter alone.
Topics in this chapter
- Nomenclature and structure of the carbonyl group
- Preparation of aldehydes and ketones: Rosenmund, Stephen, Etard, Gattermann-Koch, Friedel-Crafts acylation
- Nucleophilic addition reactions and reactivity of aldehydes versus ketones
- Aldol condensation, Cannizzaro reaction, Clemmensen and Wolff-Kishner reduction
- Tests: Tollens', Fehling's, iodoform
- Carboxylic acids: preparation, acidity and effect of substituents
- Reactions of carboxylic acids: HVZ reaction, esterification, decarboxylation
What examiners usually ask
- Distinguish between propanal and propanone using a chemical test
- Arrange the following in increasing order of acidity: CH3COOH, ClCH2COOH, FCH2COOH, C6H5COOH and justify
- Write the products of aldol condensation of ethanal and Cannizzaro reaction of benzaldehyde
Exam tip
This is the highest-weight organic chapter: prepare the eight name reactions with equations, the Tollens/Fehling/iodoform distinguishing tests, and the acidity order reasoning (electron-withdrawing groups increase acidity, their effect falls with distance).
