    Yeah but in a previous pass paper silver nitrate was used to distinguish between a long chained haloalkane and acylchloride don't know why it works but it does >_<
    I put that you add water. With the acyl chloride, you get misty white fumes of HCl, but no visible change with the other one

    Ah sh*t, I said it was because the polyester would be broken down by hydrolysis in the body and so wouldn't have to be removed once the wound had healed as they'd naturally break down…..
    I also said this

    It was 8 peaks for the carbon-13 n.m.r one right? The first box?

    I put add H20 and steamy white fumes of HCL will be seen

    There was a question like this in a previous paper in which the mark scheme answer was:
    - Chlorine is more electronegative
    - Chlorine draws electron density towards itself
    - OH bond is weaker
    Is there any chance you can find this MS?

    I said (which is in my notes/online):

    Chlorine is a very electronegative atom which withdraws the electron density from the COO- ion, making the COO- ion less negative, more stable and more acidic.

    I believe this was for two marks.

    It was 9 - did you miss out the CH3 groups on the benzene (both in one environment) as I did initially and discovered my mistake>
    Yeah I got 9 too!! Pretty sure it's right because I checked it like 3 times

    I put AgNO3. If acidified, no marks.

    Acidificed AgNO3 would work for the halogenoalkanes. However, if you don't acidify it, the acyl chloride would show a white precipitate and the Cl bonded directly to a methyl group wouldn't.

    Could the last question be CH3-O-CH2-C(CH3)2-CH2OH???

    That's what I said because the medical stuff through me off! But I think it's right though... maybe not what they want though!

    No, sorry.



    D: zero
    E: second

    People are in agreeance with E, but D people are getting 1/0 so I don't know.
    D is definetly 1 i had extra time and worked out k then put it into my own rate equation aha >_<

    Do you by any chance Remember the name of the molecule? I need to find out because i re counted at least 3 times and i was pretty sure :-(
