    Definitely better than biology, thought it was good, but I guess we'll see on results day.
    What's done is done.I didn't do a resit for bio because ill do it next year but yeah however if you didn't read the question carefully,you'd be screwed on today's exam

    That'd be great!

    Anyone else get ClO- as the ion in the bleach question, conc aq ammonia as the thing to distinguise between Br- and I-?

    Plus, the drawing, I put the dative covalent in the BF3 bit, between a fluorine and the boron, and has a double bond between the nitrogen and the boron? Not sure if this is right, but it seemed to work out alright

    Yeah it is ClO-, and conc. ammonia.

    But it's your drawing is incorrect, it's the dative covalent bond between the nitrogen and boron. All the fluorines and hydrogens are bonded singly.

    The dative covalent bond is between the Boron and Nitrogen.

    NH3 is three bonded pairs (N-H) and a lone pair of electrons. The Lone pair then acts as the dative covalent bond with Boron which is also has three bonded pairs (B-F).

    Thats what i did and seemed to work.

    That's cool thanks, I knew it was wrong someway but just couldn't make it fit.
    Ahhhh welll.

    Indeed. There were lots of intricate bits that could trip people up, or at least lead them to make lots of silly mistakes. I reckon they should have given us more time to check really, at least 5 minutes more.

    I thought it just had that idiotic verbose part question passage...

    I thought the question subsequently followed in the following way: "The student then.... They noticed that...."
    Am I wrong!?

    Even so, I feel Cyclohexane is for when distinguishing displacement reactions; not necessarily precipitation formation react ions high was clearly stated.

    I hope that it is right!
    It was only natural! It didn't take long to think of!
    If I write something down too fast, it means it definitely is natural!

    What your saying is right I think because its when you add an organic solvent and cyclohexane is organic right?

    I think to a point they were as people were learning the exams rather than the course content, now they vary the exam questions and styling that you have to know your stuff (at least what i've experienced going through past papers and real exams)

    I feel the same, somehow messed up a GCSE level question (at the beginning with Potassium). Totally misread the question that there were isotopes of potassium and ended up putting Argon (due to 18 electrons).

    Mega screw up of a mark from me
