    Ah Shieße I don't think I put + HCl
    ahh dont worry, it just said to draw the intermediates anyway! You're good!

    Edexcel enjoy watching us squirm. :'( Do you think it was easier than June 2015?


    Posted from TSR Mobile
    Can't really answer because I've honestly not done June 2015

    But I don't think this paper would have been too different, in terms of the style of questions answered (like nothing super new except [CuCl4]2- existing in hyper-dimensional space where it can have two different shapes at the same time in our 3 dimensions [Lol Edexcel]).

    The bit about melting point, is it to do with the internal hydrogen bonding?

    or maybe it was disproprtionation??????? Cuz copper went from +2 and 0 on the left to +1 on the right
    I went on to say it was 'reverse' disproportionation just to be sure

    Don please tell me that was a one marker

    I believe the equation itself was. If I'm not mistaken, I remember thinking "crap I don't know this" at first, so looked at the marks and I was relieved to see it was only 1 mark? But the bit after was deffo 2 marks

    I didn't put equilibrium arrow for the sunglasses so fml lol. And that cisplatin bs, then why there's geometrical isomers. The very last cation and anion thing idk either. That's about it that I got wrong/not sure. Might have lost a few marks for writing question for not making the point they want me to make but oh well. Fingers crossed for 100% UMS but not sure tbh

    I said 4-nitro packs better as it's more linear so stronger London forces.

    HCl is for the oxidation of the alcohol group.

    Omg me too! I thought I was wrong

    For that synthesis we only needed reagents and intermediate, so we didn't need HCl or reflux or any other bs

    The question came up in jan 2016. It's about more hydrogen bonding and internal hydrogen bonding I think, although I am not certain.

    Haha yeah me too in the same areas (except the equilibrium thing). I think I got the one about a reason for why 3 steps is better wrong (I said uses less environmentally harmful chemicals) and the one about the problem of one isomer of the drug or whatever wrong :// I know for sure that I got the MCQ about the molecular formula wrong also. But on the whole, not too bad ?!

    I thought it was because of steric hindrance due to the lone pairs on the delta negative oxygen and nitrogen being so close together so two hydrogen bonds couldnt form per molecule

    Can you remember the main Q in section B? how many were there (like big questions, not parts lol). Like the first one was about E cell and vanadium, etc.?

    In which step?

    I have no idea then, I didn't do Jan 2016 paper. Was it the same molecule?
