1. The problem statement, all variables and given/known data
Draw the two most plausible resonance forms for the following species, using arrows to indicate the flow of electrons from one form to the next. Circle the major resonance contributor. H2CNO-

2. Relevant equations
None

3. The attempt at a solution

My question is... Why is the "correct" answer more plausible than mine? I assumed that the formula was not necessarily a condensed formula because it did not state so in the question so the connectivity would not be the "same" as in the formula. Wouldn't the negative charge on the carbon of the correct answer make the resonant structure somewhat implausible?
