-NH2 is one of the most powerful ortho/para activators in electrophilic aromatic substitution. However, attempts to nitrate aniline under standard conditions leads to the formation of m-nitroaniline (3%) with 97% of aniline remaining unchanged. Why is this? Hint: -NH2 is a base as well as an activator. 3. Why are amines more activating than amides? NH2 Aniline is very readily brominated in aqueous conditions at room temperature in comparison to benzene (high temperature and FeBr3 catalysis is required). When aniline...
