    wasn't it OH + benzene and so a phenol? which would react differently to an alcohol
    darn you! i could've been perfectly ignorant of that fact now that i remember it!!! :p:

    oh well, at least there were no seals...

    haha that's true! chemistry is always so much more straightfoward than biology

    Nuffield? Not sure what that is?
    Got offered to do one of the shorter science ones for free by aimhigher notts, so took 'molecules, medicines and drugs' and passed, will hopefully prove useful
    whey molceules, medicines and drugs..just sent my eca off!

    Did anyone notice that two of the esters in the NMR question had the exact same structural formula, just reversed?!

    It was the correct answer one (CH3)2CHCOOCH3 or something lol, The other ester was the same just the other way around.

    Last question sucked!!
    I ended up making up some random formulas..
    and also, what did people get for the other observation of the bromination of phenol?
    the last questions was sooo hard! i just wrote random stuff was really running out of time,.. i said a white precipitate??? DK if thats right tho!

    It wasn't really unfair, especially considering it's actually impossible for there to be five peaks.
    Technically speaking - the five peaks could have been an overlapping multiplet in which case it could exist...but i doubt theyd ask us about that...

    Was that the bottom right in the corner? I don't remember which one i chose just that it wasn't the top right.
    Does anyone actually remember the 3 esters in that question? There was a (CH3)2CHCOOCH3 .. a CH3CH2COOCH2CH3 and one other.. can anyone remember the last one?

    what answer did you get?
    a tertiary amine form or another ester bond?
    Is the tertiary amine where you have each half of the anhydride bonded to the N and then the other bond to phenol? Is that right. That's what I put but i'm not really sure.

    There were 7 peaks....Cause it was adjacent to two CH3 groups

    isn't it just easier to call it a peptide bond?
    Isn't it just easier to call it an amide bond?

    Having five peaks, for the purpose of our course, means that there's four hydrogens adjacent. Given the fact it was an ester, and given the molecular formula, it wasn't possible for there to be four hydrogens on the adjacent carbon.

    i was speaking generally, not specific to the question (consider a H coupling to adjacent H's on two CH2 groups in the same environment)...but yes ur right..

    I said that in response to someone who was speaking about the question, so I was responding in regards to the question.
