    What was the number of peaks for lidocaine (carbon nmr)
    I think I put 9. I remember counting them and getting 10 which wasn't one of the answers so I gave it a recount!

    Just a load of one mark questions that took too long.. Odd paper with relatively simple questions at times but it's stuff that has never EVER come up.. Not amused AQA - I am going through clearing
    Totally agree!! Plus lots of questions worth around 2 marks which were worth about 4 on all the past papers, but obviously took just as long to complete!

    I found it a very hard paper but I still think I've done well in it!
    Answer to last question was something like H3COCH2CH2C(CH3)2OH
    Or that's what I got at least and I was pretty confident with it.
    Was unsure about the reaction with the diol - my answer was a cyclic compound?
    Also unsure about the question regarding the hydrogen chloride thing with the large molecule which sounded like cocaine?😂

    Pretty sure H3COCH2CH2C(CH3)2OH is correct, thats what i got anyway

    I wrote that for the last question but it's a tertiary alcohol and it can't be oxidized with potassium dichromate :'( :'(
    My answer was a cyclic compound with the diol too! yay
    The chloride thing I wrote it's more soluble? idk
    it wnt a tertiary alcohol as a tertiary alcohol cant be oxidised, and turning green would show it had been oxidised? I got that structure too

    I put k[H+] for the new rate equation, if the concentration of propanal is so high so there's a massive excess, it won't limit the rate I think?

    I was exactly the same revised loads and they go and give us that horrible paper! It was a hard paper. But I kept looking over my calculations and most of them I don't think I could have put anything else.

    Other than marks 6 marks that i found difficult and know i lost, i though that was a reasonable paper. Did anyone say electrophillic addition for the one where a aldehyde became an ether or just me?

    Also my compound for the last question had one alcohol group and one ether group...

    Ok so for the last question we know it has to be a primary/secondary alcohol because of the dichromate reaction, but the O-H nmr peak was a singlet, suggesting the adjacent carbon to the alcohol group is itself bonded to no hydrogens. Therefore how can it be a primary or secondary alcohol??
