    The aldehyde and ketone was the alternative I think because it said limiting potassium dichromate?

    Such a nice paper imo. Better than paper 1.
    It feels like 64 for an A
    But I think it will be 60. Mixed reactions from what I have seen.
    Everyone in my class found it to be a nice paper.

    I put the alcohol (whatever it was called) plus 3(O) becomes 2H20 plus COOHCOCH3

    I said that honeycomb has a large SA and a thin layer wouldnt decrease the SA so the catalyst would still be effective

    The first one will be oxidised to a ketone though? The secondary alcohol part. And your skeletal structure needs to show the diol! Or else it would be mistaken as a methyl branch
