You know for the dot point which requires you to know about a person working in a particular branch of chemistry and what principle they use?

My example is:

John Smith is a production chemist at a plant which produces ammonia through the Haber process. The branch of chemistry that he undertakes is analytical chemistry which involves the analysis of the chemical contents of substances and mixtures. A chemical principle that John will employ is that of solubility as he uses gas-liquid chromatography to identify the substances present as the gas is passed over a liquid stationary phase. If the ratio of nitrogen to hydrogen is not roughly 1:3, efficiency may be reduced. In addition, if carbon monoxide or sulfur is present, the catalyst may be poisoned, resulting in the need for it to be replaced.
Who's john smith?

Maybe i should change the verb to identify. I don't think we have to know it but it consists of TiCl3/TiCl4 and a triaklyaluminium e.g. Al(C2H5)3

How many products/polymers do you know? I'm referring to these two dotpoints:
- identify ethylene, because of its double bond, is readily transformed into many useful products
- identify ethylene as a monomer from which polymers are made

I feel like I'm underprepared (only knowing basic 4: LDPE, HDPE, PVC, polystyrene)

They're the only 4 you're supposed to know.
For the 4, you are supposed to know their common and systematic name, 2 uses with 2 related properties.

Also remember hydrogenation, hydration and halogenation?

Too generic for me :p Try this one pulled straight from the syllabus dotpoints that I think a lot of people will lose marks:

Describe the structure of cellulose (3)

Provide an answer? I don't know what to put for 3 marks.

And yes this would put off many people
