The carbonate ion, CO32 can be represented by a series of three equivalent resonance forms. Show the resonance forms of CO32 including formal charges?How many valence electrons are there in the hydrogen phosphite ion, HPO32-? (a) Draw a Lewis structure that obeys the octet rule and assign formal charges to each atom. (Hint: hydrogen atom is attached to phosphorous atom). (b) Draw the structures where the formal charges are minimized. (c) How many resonance structures are there for this ion?

5. Draw the number of resonance structures indicated, your structures must fulfill the octet rule. This exercise serves to develop a sense of which Lewis Structures are reasonable so think whether what you are proposing makes sense. Assign formal charges and determine which structure is more likely, major contributor. Draw a box around this structure. Note: it is possible to have more than one major contributor. In that case, indicate these equivalent structures by drawing a box around all of...
