    im confusing myself!
    can you have a ketone with two carbons...ethanone??!

    Nope, it would be an aldehyde.

    does not exist; it is ethanal

    Same as before, ethanone cannot exist and it would actually be ethanal. It's like saying methene exists xD

    ahhh, good old alcohols and oxidising with acidified potassium dichromate <3

    No you can't, ethanone doesn't exist. You can have ethanal however.

    A ketone is a compound that can be produced by the oxidation of a secondary alcohol - the carbonyl thus has to be on a carbon that aren't "on the edge"

    wherever you shove the double-bond-O on a 2-carbon compound it will always be "on the edge" so it will be an aldehyde. Ethanal.
