Attempt 1
One of the structures is not a
viable structure
After identifying the three structures
that can represent the formate anion,
determine which of the structures are
the major contributors to the resonance
hybrid. A major contributor to a
resonance hybrid has a greater number
of covalent bonds, has any negative
charges on the most electronegative
atom, and minimizes the formal
charges on each atom.
There are two major contributors and
one minor contributor.
