Explain the answer. 

Oxalic acid,, H₂C₂O_4, is apoisonous substance found in raw spinach. If oxalic acid has a C-Csingle bond and no C-H bond, draw its Lewis dot structure. (You maydraw bonds as lines, rather than dots, but include all lonepairs).

Next, draw Lewis electron dot diagrams for the followingspecies, indicating formal charges, and resonance diagrams whereapplicable. For resonance structures, indicate which is mostsignificant contributor. You may draw bonds as lines, rather thandots, but include all lone pairs.
