Draw resonance structures for the following compound:Add curved arrow(s) to show resonance using one of the five patterns, and modify the second structure given to draw the new resonance structure. Include relevant formal charges in your structure. Use the + and - tools to add/remove charges to an atom, and use the single bond tool to add/remove double bonds.

Please don't provide handwritten solution .....

The skeleton of the bicarbonate ion, HCO, , is shown here. Draw the complete structure. Add nonbonding electrons and formal charges where appropriate. Select Draw Rings More Erase H C H

For each resonance structure, use curved arrows to show the delocalization of electron pairs that transforms the structure into the indicated resonance structure. : + resonance structure A &-&-&-& + resonance structure B + resonance structure C resonance structure D Do not delete any pre-drawn bonds, charges, or lone pairs. If you accidentally delete a vital part of the structure, use the undo button on the lower left of the drawing canvas.

For the given compound, draw all significant resonance forms and rank them from most significant to least significant. Briefly explain the rankings. Part 1 Let's begin by considering which resonance patterns are present. First, add curved arrow(s) to show the resonance using the following pattern: a pi bond between two atoms of differing electronegativity. Modify the second structure given to draw the new resonance structure. Include relevant formal charges in your structure. Use the + and - tools to add/remove charges to an atom, and use the single bond tool to add/remove double bonds. H₂C CH₂ H₂C Edit Drawing CH₂ SUPPORT
