Yeah probably 3. would be 4 for getting the first two correct but -1 for swapping the halide. Did you write anything about E or what it can/cant be? bc that will sometimes get you an extra mark
I only said that it goes through reflux and is the products of an alcohol and carboxylic acid which is esterification so E is an ester and then I ran out of time.

I think that would be 1 more mark, and if you explain what the numbers in the h nmr just meant than that would have been another mark. So probs 4/7

what was the iodic acid and sulfamic acid question, were we supposed to know the formulas for it?
No you just had to calculate their pH by plugging in the numbers. But since it wan't equal to that 1.151 or whatever it was, it can't be a strong acid and doesn't fully ionise. Btw which one was stronger?

light work. yeah iodic acid was the stronger one (the 0.1 molL-1 one) since you need less of it to obtain the same pH as the sulfamic acid

What do you reckon you guys got raw?
In the negatives YEAHHHH!!

kidding, but in all seriousness - as i tend to do - didnt get to finish it, so i think a maximum of 30-40 for me. If that. But hey! I finished more than in trials, and i got my depth study that i did pretty okay in so- win?

Not an academic win, but a personal win! XD
