Introduction to Organic Chemistry
Organic chemistry begins with recognising carbon-based molecules, naming structures accurately, identifying isomerism and recognising functional groups. These pages separate the core naming rules, isomerism and common functional groups so that students can revise each area clearly before applying them to reactions, mechanisms and synthesis.
Revision Notes
Work through each part of Edexcel Topic 6 in a structured sequence.
IUPAC Rules
Revise how to name organic compounds by identifying the longest carbon chain, functional group, substituents and position numbers.
Start revisingAlkene
Learn how alkenes are identified by the carbon-carbon double bond and why this functional group leads to addition reactions.
Start revisingAlcohol
Revise alcohols as organic compounds containing the hydroxyl group and connect their structure to naming and classification.
Start revisingHalogenoalkanes
Review halogenoalkanes as compounds containing a carbon-halogen bond, including how halogen substituents appear in names.
Start revisingAldehyde
Learn how aldehydes contain a terminal carbonyl group and how this affects naming and structural formulae.
Start revisingKetone
Revise ketones as carbonyl compounds where the C=O group is within the carbon chain rather than at the end.
Start revisingCarboxylic Acid
Review carboxylic acids as compounds containing the carboxyl group, including the COOH structure and acid naming pattern.
Start revisingEster
Learn how esters are recognised from the COO linkage and how their names are built from the alcohol and carboxylic acid parts.
Start revisingIsomerism
Revise how compounds can have the same molecular formula but different arrangements of atoms, including structural and stereoisomerism.
