Explain the following observations about the two carbon-oxygen bonds in the methanoate (formate) anion, HCO2−. You may draw a Lewis electron-dot diagram (or diagrams) of the methanoate ion as part of your explanations.
Observation 2: The length of the carbon-oxygen bonds in the methanoate (formate) anion, HCO2−, is intermediate between the length of the carbon-oxygen bond in methanol and the length of the carbon-oxygen bond in methanal.
