The formic acid structure is expected to be the most stable, with the resonance structure playing only a small role. In the formate anion, the two resonance structures are equally likely. The steric number is three, the molecule probably trigonal planar about the C. The C-O bonds in the acid are different, with one being a double bond and the other a single bond. Those in the formate ion are basically 1.5 bonds, and we expect the C-O bond in the formate ion to be ≈ 1.3 Å, intermediate between a single and a double bond. 37.

(physical chemistry) An arrangement of bonds in a hyperconjugated molecule such that the number of bonds is the same in the two resonance structures but the second structure is energetically less favorable than the first structure; examples are H3CC+H2 and H3CCH2.

Resonance structures exist in organic and inorganic chemistry. Resonance structures refers to the ability to create (draw) a molecule in more than one way. However, one structure is usually favored over the other. Most of the time you will see these structures denoted with a (major) or (minor) next to it. This will indicate that the majority of the time that structure will be formed.
