Synthesis of organic molecules (unit 6c)

Applied Science Level 3 extended certificate (Yr13) - unit 6c (organic chemistry)

Here are some resources to help you with the portfolio work.

There are 2 key parts to the assignment work :

- synthesize (make) aspirin in the lab & purify it

- synthesize an ester in the lab (and purify it).

The key difference between the two chemicals is that aspirin is a solid and the ester is a liquid.

That means that there are slight differences in the synthesis and bigger differences in the purification steps.

Purification is really important because organic reactions rarely give high yields of the chemical that you're trying to make.  

Here are some links and video clips to get you started:
