    Thought I had it then turns out I made a tertiary alcohol :p:D
    Thats what i did! Because my structure added up with the H n.m.r it was just a joke!

    no one laugh but could it be

    (ch3)3-c-o-ch2-ch2-o-h

    i came up with that in two mins ((((((((
    Very nearly it was ch3-o-ch2-ch2-c (ch3)2 (oh)

    What were the reagents and conditions in the organic synthesis question?
    Step 3 was a substitution question to go from Br to a CN group. So I said KCN aqueous and alcohol.

    The final step was reduction, so Hydrogen & Nickel Catalyst.

    I think this is what I put:

    KCN ethanolic aqueous solution

    then

    LiAlH4 ether

    wasn't too bad? Are you sure about that?
    I hope so :/

    When I say 'wasn't too bad', I mean, compared to the potato in AQA physics last year, not too bad.

    Only the last question was a discriminator.
    Do you have nothing better to do?

    I put the same. I think because its in excess any change will be very small compared with how much there is. Is it like taking [H2O] out of Kw ?
    After some googling found out that is right, reactant in excess eliminates it from the rate equation.

    What did people put for the mechanism on the second question??
    I think it was a nucleophilic addition? The O:- accepts a proton to form a hydroxyl group.

    What everyone get for theire answers

    For the ph one i got - 3.33
    For the salt ethanoic one i got - 1.20
    For the Kc one i got - 9.09x10^3?
    I can confirm 1.20 and 9.09x10^-3

    That wasn't too bad, just a bit unlike past papers and I was REALLY pushed for time. I finished as she said 'pens down'.

    Did anyone else get the rate expression as exactly the same in the question?
    Yes
    Also, what was the reason for lidocaine hydrochloride? I said to prevent the N acting as a base by protonating it and so reduces side effects. I spent about 5 minutes looking for a chiral carbon in that compound to talk about enantiomers, but I couldn't see one!
    Oh
    I said it's a faster reaction (like ethanoyl chloride) therefore anaesthetic will work faster in the body

    For the lidocaine hydrochloride I put that the cl- makes it polar and that means it is soluble?! Really didn't know though!

    Step 3 was KCN reflux in ethanol
    LiAl4 in dry ether

    was going to put both but it said only 1 condition so ijust put alcoholic. im sure both will be right too though

    For the Lidocaine, did anyone put that it could be dissolved in water so it is able to be injected into a specific area (as it was a local anaesthetic) and that a solid tablet would not focus on a specific area ?

    I'm on here to compare my answer. Calm down, and don't talk to me.

    i think nucleophilic addition because nothing was eliminated

    Are you joking?😱
    No it won't be hope, judging by how most people found it I think the grade boundaries will be much lower than previous years. Maybe around 80-85 for A* just a guesstimate...
