Esters are organic compounds that contain the functional group −C(=O)−O−-\mathrm{C(=O)-O}-−C(=O)−O−, often shortened to −COO−-\mathrm{COO}-−COO−. They form when a carboxylic acid reacts with an alcohol.

Step-by-step lessons covering Edexcel IGCSE Chemistry Esters for IGCSE Chemistry. Each lesson works through exam-style questions in Paper 1 and Paper 2 format. Build a solid grasp of atomic structure, bonding and the mole concept early, since these underpin almost every other topic, then move on to the more calculation-heavy quantitative and organic chemistry content.
