What is the role of the nucleophile in the nucleophilic addition-elimination reaction of an acyl chloride?

In the nucleophilic addition-elimination reaction of an acyl chloride, the nucleophile attacks the electrophilic carbon atom of the carbonyl group, leading to the formation of a tetrahedral intermediate. This answer is anchored to Carboxylic acids, esters and acyl derivatives (A-level only).

In the nucleophilic addition-elimination reaction of an acyl chloride, the nucleophile attacks the electrophilic carbon atom of the carbonyl group, leading to the formation of a tetrahedral intermediate. is the best answer because it directly supports the AQA A-Level Chemistry objective to outline nucleophilic addition-elimination mechanisms for acyl derivatives. 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 nucleophilic addition-elimination 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.
