Carbon compounds and how we draw them
Carbon compounds and how we draw them

Organic chemistry studies carbon compounds, especially molecules with C−CC-CC−C and C−HC-HC−H bonds. Carbon atoms usually form four covalent bonds, so they can make long chains and rings. A hydrocarbon contains only carbon and hydrogen, while a functional group controls many of a molecule's reactions.
Step-by-step lessons covering Eduqas A Level Chemistry Organic compounds 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.
