Question:Draw all reasonable resonance structures for acetic anhydride

Short Answer

Expert verified

The process of delocalization of pi-bond throughout the structure of a compound in presence of an adjacent sp2 hybridized carbon center or a carbanion center is known as resonance. The resonance structure of allyl carbanion is shown below:
