a) Draw the Lewis structure for the molecule on the left (labeled as Molecule A above). Draw the Lewis structure which has minimum formal charges. b) Draw the correct Lewis structure for the molecule on the right (labeled as Molecule B above). Draw the Lewis structure which has minimum formal charges. c) Select the three TRUE statements from those provided below. The molecule on the right (Molecule B) is planar (all atoms lie within the same plane). The molecule on the left (Molecule A) is planar (all atoms lie within the same plane). The molecule on the right (Molecule B) has polar bonds. The molecule on the left (Molecule A) has polar bonds. We can distinguish between the two molecules (Molecule A and Molecule B) based upon their dipole moment.

Use resonance to support your choice in part (a). First, add curved arrow(s) to show the delocalization of the negative charge using the following pattern: a lone pair next to a pi bond. Modify the second structure given to draw the new resonance structure. Include 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. HO: JOH Edit Drawing HO HQ OH
Draw all resonance structures for the nitrite ion, NO₂™. Explicitly draw all H atoms. • Include all valence lone pairs in your answer. • Do not include overall ion charges or formal charges in your drawing. • Do not draw double bonds to oxygen unless they are needed for the central atom to obey the octet rule. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate resonance structures using the ↔ symbol from the drop-down menu.
) Draw a Lewis structure the molecule or ion below. Draw any resonance structures. Determine the formal charges on atoms in each of your resonance structures. Based on this, determine which resonance structure(s) are most important. Circle the most important contributor(s) to the resonance hybrid. If they are all equivalent, circle them all. COFCl
