Furthermore‚ Sammy contradicts

Synthesis of p-Nitroacetanilide (electrophilic aromatic substitution) In this experiment‚ we convert acetanilide to p-nitroacetanilide. [pic] The mechanism for the nitration is that of electrophilic aromatic substitution. The nitronium ion is directed to the positions ortho and para to the acetamido (-NHCOCH3) group. This occurs because the resonance electron-releasing effect of that group increases the electron density at those positions‚ helping to stabilize the intermediates that
