Conceptual Checkpoint 21.06 Draw the carbanion that is formed when each of the following compounds is treated with sodium ethoxide. For each, draw the electron flow arrows and the resulting enolate resonance structure of that carbanion. Then, predict whether a substantial amount of ketone will be present together with the enolate at equilibrium. Include lone pairs and charges in your answer. Do not draw out any hydrogen explicitly in your products. Do not use abbreviations such as Me or Ph.
