4.2.3
Organic
Synthesis
Section 4.2.3 brings the first-year organic chemistry together: the techniques and procedures for Quickfit apparatus, heating under reflux and distillation (a)(i), the preparation and purification of an organic liquid with a separating funnel, drying agent and redistillation (a)(ii), identifying the individual functional groups in a molecule that contains several and predicting its properties and reactions (b), and two-stage synthetic routes (c). The liquids page from 4.2.1 is included as the fourth card.
