Edexcel IAL Chemistry A2 15.8 Reactions of carbonyl compounds
Use the reagent and observation to decide whether the compound is an aldehyde, ketone or methyl ketone, then connect product structure to reduction or CN- attack.
How this is tested
- Distinguish aldehydes and ketones using Tollens, Fehling, Benedict or dichromate results.
- Use 2,4-DNPH and iodoform observations to confirm carbonyls or methyl ketones.
- Draw HCN nucleophilic addition mechanisms with CN- attack, dipoles and curly arrows.
