Carboxylic acids and derivatives (A-level only)
Question
- A. They form carboxylic acids upon hydrolysis.
- B. They react with alcohols to form esters.
- C. They do not react with water.
- D. They are stable at room temperature.
Answer
They form carboxylic acids upon hydrolysis.
Explanation
The correct option is They form carboxylic acids upon hydrolysis.. They form carboxylic acids upon hydrolysis. is the best answer because it directly supports the AQA A-Level Chemistry objective to explain acidic behaviour of carboxylic acids. This reasoning is anchored to Carboxylic acids, esters and acyl derivatives (A-level only) in Carboxylic acids and derivatives (A-level only), and it separates carboxylic acid from similar A-Level ideas rather than relying on a vague recall statement. Other options are weaker if they use the wrong evidence, calculation, mechanism, observation, unit, or conclusion for this subtopic.
Common mistake
Misunderstanding Acidic Behaviour
Students often confuse the acidic behaviour of carboxylic acids with that of alcohols, thinking both have similar properties.
Remember that carboxylic acids contain a carboxyl group (-COOH) which can donate a proton (H+), while alcohols do not have this ability.
