Using electrons and/or lone pairs in the following conjugated system, create a resonance form by moving electrons as far as possible. Modify the structure to show the resonance structure resulting from the movement of electrons. Be sure to include all lone pairs of electrons and charges. + + 0: ☑ ☐ :

Draw three resonance structures for N3-. This species has its three atoms bonded sequentially in the following fashion: N-N-N. Draw your resonance structures so that the atoms in them are bonded together in this order. Select the most important resonance structure for this species based on the formal charges on the atoms of the three resonance structures you have drawn. Now select the statement from the multiple choices which is true about this most important resonance structure.In the most important resonance structure of N3- : a) The leftmost bond (between N and N) is a single bond.b) The rightmost bond (between N and N) is a single bond.c) The formal charge on the leftmost (N) atom is -1.d) The number of nonbonding pairs (lone pairs) of electrons on the leftmost (N) atom is 4.e) The number of nonbonding (lone) pairs of electrons on the rightmost (N) atom is 4.

Draw a second resonance form for the structure shown below.   Include all valence lone pairs in your answer. In cases where there is more than one answer, just draw one.  In your structure, all second-row elements should have a complete octet when possible.

Draw 2 additional resonance structures for the polyatomic cation given.  All lone pairs and nonzero formal charges present in each resonance structure that can be drawn.  Each structure should only have one atom with a nonzero formal charge. Clearly indicate which of the 3 nonequivalent resonance structures is MOST important.
