🤓 Based on our data, we think this question is relevant for Professor Purse's class at SDSU.

Solution: There are two contributing resonance structures for an anion called acetaldehyde enolate, whose condensed molecular formula is CH2CHO-. Draw the two resonance contributors and the resonance hybrid, then consider the map of electrostatic potential (MEP) shown below for this anion. Comment on whether the MEP is consistent or not with predominance of the resonance contributor you would have predicted to be represented most strongly in the hybrid.
