Edexcel IAL Chemistry A2 15.12 Reactions of carboxylic acids
Match each reagent to the functional-group change: reduction to alcohol, salt formation with bases, acyl chloride formation with PCl5 or esterification with alcohols.
How this is tested
- Choose LiAlH4 in dry ether to reduce carboxylic acids to primary alcohol products.
- Write acid-base equations with carbonates or hydrogencarbonates and identify CO2 gas.
- Use PCl5 fumes or alcohol plus acid catalyst to identify acyl chloride or ester formation.
