WebbThe carbon para to the nitro group is more reactive because the negative charge that is created can be delocalized into the nitro group. What is an electrophilic aromatic substitution? the reaction between a nucleophilic aromatic ring and an electrophilic reagent. As a nucleophile, electron donating groups on the aromatic ring increase reactivity. http://www.chem.ucla.edu/~bacher/spectrocopy/IR1.html
