- A. Hydrogenation using H2 and a catalyst
- B. Dehydrohalogenation using NaOH
- C. Oxidation using KMnO4
- D. Hydrolysis using HCl
Answer
Hydrogenation using H2 and a catalyst
Explanation
The correct option is Hydrogenation using H2 and a catalyst. Hydrogenation using H2 and a catalyst is the best answer because it directly supports the AQA A-Level Chemistry objective to plan synthetic routes between organic compounds in the specification. This reasoning is anchored to Synthetic routes (A-level only) in Organic synthesis (A-level only), and it separates plan 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
Incorrect reagent selection
Students often choose reagents that do not facilitate the desired reaction in the synthetic route.
Review the reactivity and compatibility of reagents with the functional groups present in the organic compounds involved.
