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.

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