    Wait, doesn't each carbon in Benzene have 1 hydrogen attached? So each proton has two carbons each with a proton, so the splitting is a triplet?
    im sure benzene would have only one singlet because all the protons are equivalent and equal protons don't split each other

    Also Acid Hydrolysis,
    H20 and HCL right ?

    any acid catalyst yes, and heat/reflux

    Got a feeling the mechanism for the bromination of cyclohexene may come up. Don't think i've seen it before in one of the new spec papers.

    is that just Br-Br being polarised as it approaches a double bond (electron dense area), double bond breaks to form C-Br bond, Br-Br bond breaks heterolytically and the + charge left on the other carbon reacts with the negatively charged bromine thats left over?

    In last years paper, they had to explain what was happening in the Mechanism and what the curly arrows meant.
    Will we have to do the same?

    u have to know that curly arrows represent the movement of a lone pair of electrons

    Nope p14 of the textbook.

    Spot on Stevo. Remember to show the curly arrow coming from a LP of electrons on the bromine to the carbo cation during the second stage.

    btw be careful where you draw the curly arrows come from, theyre not allowed to come from a charge, have to come from a lone pair you've drawn or a bond
