Question:

Several of the compounds in Problems 25 and 28 can have resonance forms. Identify these molecles and write an additional resonance Lewis structure for each. Use electron-pushing arrows to illustrate how the resonance forms for each species are derived from one another, and in each case indicate the major contributor to the resonance hybrid.
