    What did people put for the test for carboxyl groups? I put tollens then crossed it out and put 24dnph and bradys reagent which causes orange precip. if aldehyde or ketone present and none if carboxylic acid.
    Yes, 2,4-dnph is correct. Orange precipitate.

    question 1 part b) how many products of hydrolysis did you get? and were they all carboxylic acid salts?

    im sure the equation was aminophenol + br2-----> the dibromoaminophenol complex +h2 ? anyone it balanced when I counted it

    Also does anybody know if Brady's reagent on its own be okay for the mark for the chemical test

    That's what I put, 2Hs are eliminated.

    Isn't this the answer for the last question? Someone else has the ester functional group the wrong way round

    I put 2Br2 for the reactant and 2Hbr for the other product

    I put the amine+ 2Br2 -> given structure + 2hbr

    That is the correct way, O should be next to the benzene.

    This is what I got for the NMR one at the end, how many marks do you think I will get for it?

    Attachment 228201

    Apart from that I am hoping it went okay, I struggled on the diazotisation one but then after reading the question it was obvious, I am guessing CuI was the reagent!

    1,2,3 propan- tri - ol was the systematic name I put. apart from that I didn't see any curveballs, hoping I did well but there is always a way to mess up exams and I am sure I have found it, any unofficial mark schemes being made?
    I got that at first but then I think I changed it because the peak for the HC-C=O had a relative peak area of 1 which meant it had a H attached to the C, so if the ester group was stretched to the benzene ring there couldn't be a H in that area. I'm not sure if I'm right though

    Hmm, now I think about it that's what is is usually for phenol and bromine, so I'm thinking that might've been correct
