AQA A2 Unit 4 - Organic Synthesis notes :-)Watch
For example, starting off with ethene, you can get ethane, which can then give you ethanol. You can oxidise this to give you an aldehyde then a carboxylic acid. This then can be used to make an ester and so on. On your map use different colours for the names and labelling the mechanisms. Also put down all the reagents required, and use a specified colour for the functional groups.
I suggest you may need to do a separate map for aromatics and amines, but with a bit of thinking you might be able to combine it all to make one map.
Hope that helps.
