consider the resonance structures of formate. the first lewis structure of formate has a central carbon atom. a hydrogen atom and two oxygen atoms are bonded to the carbon atom. the bond between carbon and hydrogen is a single bond. one of the bonds between carbon and oxygen is a single bond and the other bond is a double bond. the single bonded oxygen has three lone pairs of electrons and a negative one charge. the double bonded oxygen has two lone pairs of electrons. the second lewis structure of formate has all of the same atomic connectivity, but the double and single bonds between oxygen and carbon are switched from the first structure. select the true statements about the resonance structures.
