6.2.5: Organic synthesis

#6.2.5a

the techniques and procedures used for the preparation and purification of organic solids involving use of a range of techniques (see also 4.2.3a) including:

(i) organic preparation

  • use of Quickfit apparatus
  • distillation and heating under reflux

(ii) purification of an organic solid

  • filtration under reduced pressure
  • recrystallisation
  • measurement of melting points

PAG6

#6.2.5b

for an organic molecule containing several functional groups:

(i) identification of individual functional groups (ii) prediction of properties and reactions

Learners will be expected to identify functional groups encountered in Module 6 (see also 4.2.3b).

#6.2.5c

multi-stage synthetic routes for preparing organic compounds.

*Learners will be expected to be able to devise multi-stage synthetic routes by applying transformations between all functional groups studied throughout the specification. Extra information may be provided on exam papers to extend the learner’s toolkit of organic reactions. *
