What to Focus On
- Aldehydes have the group RCHO and suffix -al.
- Ketones have the group R2CO and suffix -one.
- Carboxylic acids have the group RCOOH or ArCOOH.
- Carbonyl carbon is sp2-hybridised.
- Carbonyl groups are planar with ~120 degree bond angles.
- Carbonyl carbon is electrophilic and oxygen is nucleophilic.
- Primary alcohols on oxidation give aldehydes.
- Secondary alcohols on oxidation give ketones.
- Rosenmund reduction converts acyl chlorides to aldehydes.
Common Mistakes to Avoid
All aldehydes give Fehling's test.
Benzaldehyde is more reactive than propanal because aromatic compounds look more activated.
Ketones react with Tollens' reagent just like aldehydes because both contain a carbonyl group.
