The more likely resonance structure for SeO3^2- is A, B, or C?

Use formal charge and electronegativity to identify best resonance structure. Three inequivalent resonance structures for the selenite ion, SeO_3^2 -, are shown below. Assign formal charges to all atoms in the resonance structures and identify the more likely resonance structure. A B C Se _______ _______ _______ O_1 _______ _______ _______ O_2 ______ ______ ______ O_3 _______ _______ _______ The more likely resonance structure for SeO_3^2 - is _______.

For all resonance structures: include lone pairs and show formal charges, if any. a. Ozone, O_2, has two equivalent resonance structures. Draw both resonance contributors. b. Draw three equivalent resonance structures for the nitrate ion, (NO_3)- c. Draw a Lewis structure for acetaldehyde, C_2H_4Othen draw a non-equivalent resonance structure. Label each structure as major or minor contributor. Draw all resonance structures for the carbocation below. Used curved arrows to show the movement of electrons from one resonance form to the next. Include all non-zero formal charges for each structure that you draw. Which ion is more stable? Use resonance theory to illustrate how the ionic charge may be delocalized.
