  • Benzocaine
    aromatic ether involves the esterification of a benzoic acid in the presence of acid. The benzoic acid is not reactive enough to undergo nucleophilic addition so a strong acid is required to protonate the carbonyl oxygen, which gives it a positive charge, thus making the molecule more reactive. The...
