Booklet for unit 28 M3 D3. Organic synthesis maps. Main reactions in organic chemistry:. If you are aiming for M3…. You need to be able to plan a synthesis route and draw up a synthesis map EXAMPLE:
Organic synthesis maps
Plan a synthesis route with Ethene as your starting molecule and Ethanal as your target molecule
Plan a synthesis route with Ethene as your starting molecule and Ethanal as your target molecule.
Heat with conc. H2SO4
Add ethanol to acidified dichromate (VI) and distil
In the step of changing ethanol to ethanal, there is a risk of ethanoic acid being made instead if excess acidified dichromate (VI) is used and if the reaction is refluxed instead of distilled.
TASK: Plan a synthesis route involving two or more steps between the starting and target molecules listed below.
For M3: Draw up a synthesis map for your answer.For D3: Add details on reaction conditions to your synthesis map and comment on likely yield of final product.
