Quick explanation
Outline nucleophilic addition-elimination mechanisms for acyl derivatives
- This point belongs to Carboxylic acids and derivatives (A-level only), especially Carboxylic acids, esters and acyl derivatives (A-level only).
- You need to be able to outline nucleophilic addition-elimination mechanisms for acyl derivatives.
- The key ideas to know are nucleophilic addition-elimination.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Key concepts
Why it matters
This objective helps connect Carboxylic acids, esters and acyl derivatives (A-level only) to exam-style questions, flashcards, and revision notes for Carboxylic acids and derivatives (A-level only).
Quick student answer
Which of the following is a correct nucleophilic addition-elimination mechanism for the reaction of an acyl chloride with water?
Direct answer
A. The acyl chloride reacts with water to form a carboxylic acid and hydrochloric acid.
Key terms
- Nucleophile: A species that donates an electron pair to form a chemical bond in a reaction.
- Acyl chloride: A derivative of carboxylic acids where the hydroxyl group is replaced by a chlorine atom.
Common trap
Confusing acyl chlorides with carboxylic acids: Remember that acyl chlorides are more reactive than carboxylic acids and can form esters and amides through nucleophilic addition-elimination.
