Compare the bonding in formic acid (HCOOH) with that in its conjugate base formate ion (HCOO). Each molecule has a central carbon atom bonded to the two oxygen atoms and to a hydrogen atom. Draw Lewis diagrams, determine the steric numbers and hybridization of the central carbon atom, and give the molecular geometries. How do the orbitals differ in formic acid and the formate molecular ion? The bond lengths of the CO bonds in HCOOH are 1.23 (for the bond to the lone oxygen) and 1.36 (for the bond to the oxygen with a hydrogen atom attached). In what range of lengths do you predict the CO bond length in the formate ion to lie?
