Consider the formate ion, HCO2-, which is the anion formed when formic acid loses an H+ ion. The H and the two O atoms are bonded to the central C atom.
(a) Write one or more appropriate Lewis structures for this ion.
(b) Are resonance structures needed to describe the structure?
(c) What would you predict for the bond lengths in the C-O formate ion relative to those in CO2?
