    ok, firstly:

    how could methylbenzene be converted into benzenecarboxylic acid? state the type of reaction and suggest a suitable reagent

    and:

    how could phenylethanone (C6H6COCH3 if i'm not mistaken) be converted into 1-phenylethanol? state the type of reaction and suggest a suitable reagent

    i have looked through all my books and on the net, and couldn't find anything so am left feeling a little puzzled (i look like this: :confused: )
    i'm grateful for any help. cheers

    yeh same here-the chem course is so short-at least for OCR that is (Nothing like OCR Biology )

    It is a side-chain oxidation. Reagents: Potassium Manganate (VII) in alkaline solution

    I think it's a reduction reaction. Reagents: LiAlH4 [Lithium Tetrahydridoaluminate (III) ]in dry ether


    I havent done chem since June so i am not TOTALLY sure about the answers.

    You must state that the permanganate solution is hot (probably by using the triangle symbol). It's just an oxidation not a side-chain oxidation (thought I doubt you'll lose marks for this). You can also use a Cobalt (Co) catalyst at 140oC whilst bubbling oxygen through the toluene - this gives you a purer product (the ketone is a side product in the other reaction).

    I think it's a reduction reaction. Reagents: LiAlH4 [Lithium Tetrahydridoaluminate (III) ]in dry ether
    or NaBH4 sodium borohydride - it's a bit gentler than Lithal. Don't worry about the solvent as the question doesn't ask for it.

    Pretty good nonetheless!

    Are you considering taking Chem further, if so I would recommed solomons organic chemistry as a good basic book.

    Please do chemistry then, we need more people with a passion for the subject. Chemistry is amazing and it gets even more interesting the further up the educational ladder you climb. Job prospects are second to none too.

    When I was at school everyone else in my A-Level class was either medic, dentist, vet or engineer - it's depressing that out of my whole year of 120 I am the only person with a chemistry degree. Even if you want to do medicine it's still possbile after a chem degree (grad med school) and you'll be streets ahead of the other doctors. I've seen a lot of potentially great scientists wasted on medicine.

    Hey, there's lots of other medical places you can go into where you can use your chemistry talents. Have you considered doing Pharmacology? That way you can make all the medicines that the doctors use (and they're the things that are really improving the quality of life of the patients out there). If you're not sure about doing Chemistry I'd recommend doing work experience somewhere like GlaxoSmithKline if they're nearby. Alternatively GlaxoWellcome, Allen&Hanbury or that other one... argh, I can't remember the name but I think it had Proctor in it (damn these merging multicorporations!)

    Hehe, I've probably just confused you even more, but seriously - there's so many prospective doctors studying out in the world that the competition for Uni places is extremely strong. If there's any blemish in your academic record then they may find an excuse to reject you (sadly ) - and remember that you can only apply for 3 medical/dentistry courses on your UCAS form so it's good to have a backup plan! Immunology or Pathology might suit you too as it's medically-based but there's a lot of chemistry involved in immunological attack/defense
