Draw the Lewis structure (including resonance structures) for diazomethane (CH2N2). For each resonance structure, assign formal charges to all atoms that have formal charge. Draw the molecules by placing atoms on the canvas and connecting them with bonds. Include all lone pairs of electrons. Show the formal charges of all atoms in the correct structures.

1. Write the "best" Lewis structure (minimize formal charge, maximize number of resona structures) for the following species. Include formal charges on all atoms having any and give resonance structures. When appropriate, expand the octet to reduce formal charges and gain resonance structures. Give the electronic and molecular geometries for each and determine i they are polar or nonpolar. NO2 SO32- PO43- 2. Use formal charge to determine which Lewis structure is better: H-5--H H- -3-H

PhET Simulation - Build a Molecule ③ 17 01 25 G Part B For many compounds, it is possible to draw multiple Lewis dot structures that are simplifications of the structure of the true molecule. The actual structure of the molecule, caled a resonance hybrid, is a combination of all of the different structures, which are called resonance forms. The cyanation (OCN ) is capable of forming three different resonance forms Draw Lewis dot structures for the three possible resonance...
