N ucleophilic Aromatic Substitution Michelle Hamilton
Aromatic r ings normally undergo electrophilic substitution due to high pielectron density. The previous experiment was an electrophilc reaction, however a romatic r ings will undergo nuc
Experiment 9A INTRODUCTION
Electrophilic Aromatic Substitution
One of the most common and useful electrophilic aromatic substitution reactions is nitration, which introduces the nitro group (NO) on to the aromatic ring HNO + 2HSO NO + HO
