Carboxylic Acids & Esters | A Level Chemistry Ultimate Guide

Description Introduction
This A Level Chemistry lesson covers carboxylic acids and esters in detail, including nomenclature, reactions, mechanisms, and applications. You will explore acid strength, ester formation, hydrolysis, acylation, and nucleophilic addition elimination. Ideal for revision, consolidation, and exam preparation for all exam boards. Made with AQA in mind but fully relevant to OCR, Edexcel, and international specifications.

Comprehensive Overview
In this A Level Chemistry masterclass, you will develop a complete understanding of carboxylic acids and esters. The video begins with formulae, nomenclature, and worked examples, before exploring weak acid behaviour and factors affecting acid strength.
You will then move on to esters, including naming, isomerism, and methods for synthesising esters. The lesson covers ester hydrolysis in both acidic and alkaline conditions, including detailed mechanisms and applications such as soap production and biodiesel formation.
Finally, the video introduces acylation and nucleophilic addition elimination reactions, with step by step mechanisms for reactions involving acyl chlorides and acid anhydrides. This video is designed to strengthen exam technique, deepen understanding of organic chemistry, and prepare you for higher level exam questions.
