1. The problem statement, all variables and given/known data
Which has a greater C-O bond length, formate ion or carbonate?


2. Relevant equations
... resonance?


3. The attempt at a solution
After drawing the lewis structures, I found the resonance of both... but I don't get how they have somewhat "equal" bond lengths (according to my teacher)
