The -NH2 group is a very strong o,p-directing activator in electrophilic aromatic substitution reactions. However, when aniline is subjected to standard nitration conditions, poor yields of m-nitroaniline result. Clearly, the reaction conditions are influencing the directing effect of the -NH2 group. Explain why this occurs, using both words and structures.
