    It wants you to say that there is an alcohol and an alkene (double-bond). Functional groups govern the reactivity of organic molecules, since the C-C and C-H skeleton is pretty unreactive.

    you'll get the subject soon enough- just be sure to remember all of those damn reactions and equations

    Right sorry I have 1 last question:

    draw diagrams of two isomers of C4H8 each of which are structural isomers of but-2-ene. Name each isomer.

    Anyone? :confused:

    i dunno how to draw on the computer so i'll have to explain it..sorry!

    draw ur basic c=c group, and draw either
    A) 2 methyl groups (CH3) attached to 2 different carbons, CIS/TRANS, OR;
    b) 2 methyl groups (CH3) attached to the SAME carbon
    C) an ethyl group (CH3CH2) attached to a carbon- making a 4 carbon chain (but-1-ene), with the c=c group at the end

    COMPLICATED, but hope it gives u some guidance

    ha! thanks rainjan, godess of chemistry! :cool:

    I looked around a bit and i've come up with this:



    I think that's about right, I hope :p: :cool:

    'godess of chemistry' LOL

    IT TOOK ME AGES TO GRASP SOME REACTIONS- believe me, there is worst to come- but yeah, ur pics are correct- except if you move one of the CH3 groups across the double bond and fiddle with the other then u get geometric isomers (cis/trans)- u'll have to know about them

    its hard but youll get it,and come out with an easily obtainable A- like me

    just stay on top of the class by doing the extra bit of revision- which i didnt do, so it was surprising that i passed it at all!
