Nucleophilic aromatic substitution involves the formation of a resonance-stabilized carbanion intermediate called a Meisenheimer complex as the nucleophile attacks the ring carbon carrying the eventual leaving group; electron-withdrawing groups ortho and/or para to the site of attack help to stabilize this structure via resonance. For the reaction below, draw the structure of the stabilized reaction intermediate in the box below. You do not have to consider stereochemistry. Draw the Meisenheimer complex with a formal charge of 0 on the nucleophilic atom. If more than one resonance structure is possible, only draw the most important one.
