Chapter 1, Problem 29

(choose chapter or problem)

(a) The structure of the bicarbonate (hydrogen carbonate) ion, HCO32, is best described as ahybrid of several contributing resonance forms, two of which are shown here.OO OO HO HO(i) Draw at least one additional resonance form. (ii) Using curved electron-pushing arrows,show how these Lewis structures may be interconverted by movement of electron pairs. (iii) Determinewhich form or forms will be the major contributor(s) to the real structure of bicarbonate,explaining your answer on the basis of the criteria in Section 1-5.(b) Draw two resonance forms for formaldehyde oxime, H2CNOH. As in parts (ii) and (iii) of (a),use curved arrows to interconvert the resonance forms and determine which form is the majorcontributor.(c) Repeat the exercises in (b) for formaldehyde oximate ion, [H2CNO]2.
