    Phenol with ethanone joined together. for C NMR.
    https://www.thestudentroom.co.uk/att...2&d=1497870262


    For this I think it's wrong because on this picture you have 8 carbon environments and you needed 6 because there were only 6 peaks so you needed to put OH where it would make 6 environments
    That is 6 dude

    If you're talking about the one where we draw the repeat unit with why it is easily biodegradable, that was 3 marks, assuming 2 for the repeat and 1 for the reasoning.

    If you're talking about drawing the separate compounds in the repeat unit shown, that was 2 marks, 1 for each.

    Hope you did well!

    Thankyou! It went well i think. How did you find it?

    There was a question below the two monomers about the number of repeat units there was. Just checking cos I missed it out

    What was the answer to the multiple choice about 0.1 mol and 0.1 mol makes how many atoms?
    6.02x10^22 i believe

    0.1 x 6.02x10^23 = 6.02x10^22

    Highest ive seen in past papers is 92-A*, 87-A, 76-B but then again who knows how everyone found it

    For the IUPAC I had trouble naming the compound. I wrote hexene-3-ol. Would this suffice?

    I put 6.02x10^22 because the ratio was one to one but I've seen other people put 3.01x10^22 so idk anymore

    but there was no C-O bond in the CNMR diagram, so how could it be phenol??
    i think its different for carbons in benzene not sure tho

    If i put "the impurities crystallize out" for the six marker but put everything else correctly, how many marks would i lose?

    Some random answers:
    6.02*10^22
    Ch3Ch2COOCH2c(CH3)3
    Carotene saturated had 78 hydrogen and unsaturated 56 hydrogen
    But-3-ene-1-ol
    95 repeat units
    Phenylethanone with OH group opposite
    Silver nitrate solution
    HCL/H20 for hydrolysis, NaBH4 for reduction and sn/concentrated HCL for reduction of NO2 group
    (can anyone remember the naming Of The cyclic compound)
    4 chiral carbons
    Like 71% yield, you can recrystallise by dissolving in the solvent then filtration under reduced pressure, before testing for purity by taking the melting point and comparing to known values
