🧠 Memory Aid: -COOH = Acid, -anoic acid Ending
Two simple rules to remember carboxylic acids:
- Functional group = -COOH (carboxyl group)
- Naming = same prefix as alkane + "-anoic acid" ending
Meth-anoic, Eth-anoic, Prop-anoic, But-anoic acid
Test for carboxylic acids: Add sodium carbonate — "If it fizzes, it's an acid". The fizzing is CO₂ being produced.
Oxidation pathway: Alcohol → [oxidise] → Carboxylic Acid. Think: wine (ethanol) + air (oxygen) → vinegar (ethanoic acid). Oxidation goes UP the functional group "ladder".
