It was actually a reasonably nice NMR question that quite a few people seem to have got right!![]()

Hypothetically speaking of course, but, if someone, certainly not me, were to have calculated the total entropy change correctly, then somehow managed to round it to a value it didn't even round to and then write that on the line, would they still give the mark when they saw the correct answer, and just ignore the incorrect answer written on the line?

ahh run out of time, missed out the last 2 pages on calculations and enthalpy diagram thingy completely! Plus so aanoyed with myself for not revising easy stuff like that curly arrow diagram.. I had to improvise but hopefully will get me a couple of marks :/ Also, I hate 1 markers and there were quite a few ...

What was the first answer to the question? It was a challenging but then again simple start to the exam?
I put phenyl amine, then drew a phenol with 2 amino groups, then temperature below 5 degrees and then electrophillic substituiton and then was was the next one about the prediction??? -

Anyone else feel like the 4 mark questions looked simple until you started writing and realised an easy question takes hours to write? Haha. The paper was okay, although CF6 was a crazy-arse dot cross diagram, and the mass calculation at the end was beast. I skipped over a few questions, but it went okay overall I think. I absolutely hope the grade boundary isn't too high. The entropy question and the fuse part was odd, S(total) was very large and +ve, then they went and asked about a fuse just to **** with you. Who else made up a load of bull for the farmer question too?

What did everyone get for the mass? I got 12g.
I got it through n = V x C / 1000 then n = m / Mr?? -

I got ph7.2 for the buffer question
Intermediate question - Halogenoalkene» alcohol » carboxyllic acid
What did people circle for the pharmacophore? I circled the carboxyllic acid bit :/
I got 112kg for the mass question at the begining
The first ever question was benzene ? Coz it said ORGANIC -

Octahedral! I think the bond angle was supposed to be 90 but I put 190.5. Fail. -
