- Heating under RefluxHeating under reflux lets a reaction mixture be heated for a long time without losing volatile reactants or products.
- DistillationDistillation separates a liquid from a mixture by boiling it and condensing the vapour.
- Using a Separating FunnelThe crude product of an organic reaction is often mixed with an aqueous solution.
- Drying an Organic LiquidAfter separation, the organic layer still contains traces of water, which make it look cloudy.
- Redistillation and PurificationAfter washing and drying, an organic liquid is nearly pure but may still contain other organic compounds, such as unreacted starting material or…
- Identifying Functional GroupsA functional group is the group of atoms responsible for the characteristic reactions of a compound.
- Two-Stage Synthetic RoutesSometimes a target compound cannot be made from the starting material in one step.
- Predicting Properties from Functional GroupsOnce you have identified the functional groups in a molecule, you can predict how it behaves.
