Detailed and comprehensive notes on units 3.3.8 and 3.3.9 (aldehydes and ketones & carboxylic acids and derivatives) for AQA A level chemistry. Covers: aldehydes, ketones, esters, acyl chlorides, acid anhydrides, amides, N-substituted amides and acylation reactions. Includes mechanisms with reactions conditions and drawings. I hope that you find this resource useful.

There are lots of random reactions in AQA A level chemistry that appear throughout the course, which could come up in your exams. Whilst it's not essential to have all of these equations memorised, being familiar with these equations will surely have a great impact on your performance, allowing you to answer certain questions spontaneously and spend less time figuring things out. At the very least, its important that you can derive these equations yourselves from just the reactants, as exam que...
