Good point. Perhaps my correction was wrong.. I completely skipped over the fact that it had to be secondary or primary.. But I cannot see it being any other than a tertiary due to the number of peaks and the data given:/
For the test for the acyl chloride, I put silver nitrate then white ppt. Do I get that or did the silver nitrate have to be acidified/aqueous or something?
Are you sure no2 has a negative charge because in friedl crafts acylation, h2so4 also acts as a base: h2so4 + hno3 ---> no2+ +h2o + hso4- And no2+ is formed
I put silver nitrate in aqueous solution. Forming white ppt for the halo alkane and nothing for the acyl one.
im pretty sure you can also say for the acyl chloride, using water/ammonia/alcohol/primary amine' would give you Misty fumes and for the ketone/ haloalkane; no reaction
I think the answer will probably be that the polyester can biodegrade in the wound over time because it is hydrolysed. This means it doesn't have to be removed. Not sure if this is correct though...
I'm glad that you did well but it definitely was a hard paper compared to previous years, many people found it hard so the boundaries will be low
It was a joke, one of my favorite sources of entertainment is boasting for getting 100% in really hard tests, although its funnier in real life...
In reality I did terribly in that paper, but chem5 is much easier than chem4 imo so ill have to make up for it. I got an A at AS and i think this paper was a high D low C, so with good chem 5 i might scrape aa low A or high B.

yea thats what I wrote, about the biodegradability
