    I asked of that as well to my tr but she wasnt sure but its just for the purpose of adding H+ ions so I personally think either one would be fine but just to be safe say and if it comes up👍

    I believe I got 57-58+ in that exam. I'm not sure really. I'm quite good at chemistry, it's my strongest subject, and always has been, however the problem for me was the multiple choice as well as the amount of stuff you needed to do in such a short time. I almost ran out of time, which led me to making careless errors as well as screwing up many multiple choice questions. So definitely not easy, I hope the boundaries are lower because of that, and I hope this one is a bit nicer

    It went quite well! I didn't really get a few questions on uncertainty of a thermometer and had to guess two multiple choice questions but it wasn't nearly as bad as the first one in my opinion, I've always been better at organic though so it's hard to tell

    It was all good up until the end of section A... Almost ran out of time so had to be quick. Only 10 mins on Section B but that bit seemed easy...So hopefully ok...I only have to get a C or higher so I should have at least got that

    I put the alcohol as the highest because hydrogen bonds so strongest intermolecular force, then the aldehyde(I think it was an aldehyde can't remember for sure though) because permanent dipole-dipole forces dominate and are stronger than the van der waals forces which are in the alkane, not sure if this is right though as in one of the specimen papers they stated that the van der waals dominated but I decided to go with what I knew and made sense most to me

    Guys for the propane-1,2-diol question, was the organic product formed in part a a carboxylic acid-ketone combination and for the alternative organic product it's a aldehyde-ketone combination?
