The carbon–oxygen bond lengths and the equal negative charge on oxygens of an acetate ion are to be explained by drawing resonance structures. Concept introduction: Resonance is the phenomenon of describing delocalized electrons in certain molecular ions through various forms or resonance structures and the forms contributing to the hybrid form. The positions of electrons are different, without effecting the positions of the nuclei. The effect of delocalization is caused by resonance, where the negative charge is distributed among the oxygen atoms in a carboxylate ion. The rules for drawing resonance structures are as follows: Only nonbonding electron pairs and pi electrons can participate in conjugation in the formation of various resonating structures. The single bonds present in the molecule do not break or form in the resonance structures. The placement of atoms present in the molecule remains fixed. The octet of all atoms is completely filled.

Draw all resonance contributors for each of the following molecules or ions. Be sure to include the curved arrows thatindicate which pairs of electrons are shifted in going from one resonance structure to the next.(a) CH3NO2(b) CH3CO-2(c) CH3CHCHCH-2(the ion has two C-C single bonds)(d) C5H5N (a ring is formed by the C and N atoms, and each H is bonded to C)(e) C4H5N (a ring is formed by the C and N atoms, the N is bonded to one H, and each C is bonded to one H)

Consider Lewis formulas A, B, and C:(a) Are A, B, and C constitutional isomers, or are they resonance contributors? (b) Which have a negatively charged carbon? (c) Which have a positively charged carbon? (d) Which have a positively charged nitrogen? (e) Which have a negatively charged nitrogen? (f) What is the net charge on each?

4. (i) On the structure below, add all missing lone pairs of electrons, assuming that all of the formal charges are correct. (ii) Draw line-angle structures for all resonance forms (including minor, but still significant) using appropriate notation, including double-headed resonance arrows and curved arrows for electrons. (Hint: Draw two more) (iii) Rank the three structures from most =1 to least =3 important.
