## 6.5 Draw a Resonance Structure Using Curved Arrows

In this image, the task is to draw a resonance structure of a molecule using curved arrows.

### Description of the Molecule and Symbols

- **Molecular Structure**: The molecule shown is a carbanion, with a negatively charged oxygen atom (indicated by the negative sign) double-bonded to a carbon atom. This carbon atom is also single-bonded to another carbon atom in an ethyl group (illustrated as two lines connected to the central carbon).
- **Curved Arrow**: The curved arrow is not present but would typically demonstrate the movement of an electron pair. In a resonance structure, such arrows indicate shifting electron pairs between atoms.
- **Resonance Arrow**: Located between the two structures, the double-headed arrow (↔) signifies that the two structures are resonance forms of the same molecule, meaning electrons are delocalized between these forms.

### Objective

To complete the task, the user should draw additional structures on the right, using curved arrows to show possible electron movements that result in equivalent resonance structures. This exercise helps in understanding how charge can be distributed and stabilized in a molecule.
