What makes an isomer a stereoisomer?
An isomer has the same molecular formula as another compound but a different arrangement of atoms. The first question is whether the atoms are connected differently or connected the same way but arranged differently in space.
Step-by-step lessons covering Eduqas A Level Chemistry Stereoisomerism for A Level Chemistry. Each lesson works through exam-style questions in Component 1, Component 2 and Component 3 format. Build confidence with atomic structure, bonding and moles calculations early on, since these underpin the more demanding organic mechanisms, equilibrium and practical-analysis topics that dominate Year 2.
