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

    Nope, it would be an aldehyde.
  3. Offline

    does not exist; it is ethanal
  4. Offline

    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.

    thats why i was getting confused! i kept trying to draw the structure for it and thought 'why is it an aldehyde?!'
    cheers everyone
