    I may be remembering wrong, but if the product was an aldehyde, a carboxylic acid or a ketone, then the answer was definitely acidified potassium dichromate and heat with reflux/distillation.
    It was the reaction of carboxylic acid which made something else which had a -diol and 2 double oxygen bonds ....... So it couldn't be K2Cr2O7 because that's for oxidation of an alcohol to form a carboxylic acid

    i swear it was a dehydrated Di-ol
    Dehydration would be going from an alcohol to an alkene, but this was oxidisation of the alcohol to a carboxylic acid. I think :P

    hmm... I sat for the same paper, but the questions seem different. Was there a weird Iodine monochloride titration question in Section C of your paper?

    Actually, now that I remember, it was the reaction of a diol to form a dicarboxylic acid. Which I think does react in that way.

    yeah i rushed and just saw a double bond and thought it was dehydration ;/ will i get a mark for saying heat under reflux? :/

    I got a positive number in the 70s ?? See, i didn't know which way the arrows were supposed to go so I did it like it was a formation reaction

    I got all 4 but Im not sure if they're correct:

    1) CH3-CH2-CH2-CH2-CH2(OH)

    2) CH3-CH2-CH(CH3)-CH2(OH)

    3) (CH3)3-C-CH2(OH)

    4) (OH)CH2-CH2-CH(CH3)-CH3

    Anyone know the answer, I think to the dehydrating agent multiple mark question? I think I put Na2SO4, which was D? I can't remember the options. I just remember reading that H2SO4 is a good dehydrating agent in a book and Na2SO4 seems similar?????????
