I am writing the Lewis Structure diagram for CH3COOH.
I wrote it like this:
but the answer key has:
Are both correct?
If indeed you were asked for the diagram for CH3
COOH, then there is a clue in the fact you have a CH3
and similar groups mentioned. If however it was C2
you were asked for, you may have a case. Note that carbon-carbon double bonds linked directly to a hydroxyl group are generally unstable though.
