    But isn't Nucleophilic Substitution when the nucleophile has a lone pair of electrons? HBr doesn't have a lone pair of electrons? I'm so confused.
    No but it has a negative charge due to being paired with a Hydrogen and being an electronegative element. The delta negative charge attacks the positivity of the carbon atom causing substitution to occur.. I think :eek:

    I didn't really like this paper much :o:

    I put initiation which is wrong. But I think it may have been propagation, not sure though.

    I'm not sure. I can't remember most of the questions. My brain has blocked it all out :erm:
    It seems quite a few people struggled as well.

    I think I was ok up to the article. Then I failed :cry:

    I put water and a catalyst of hot temperature and pressure. I think refluxing with concentrated sulphuric acid is also right. I remember it can be either one.
