Show the detailed mechanism for the formation of benzocaine from p-aminobenzoic acid.
What is the reaction name, and mechanism name?
A) Explain why p-aminobenzoic acid precipitates when H₂SO₄ is added to the solution.
B) Explain why the amino group of p-aminobenzoic acid does not participate in the reaction.
C) Explain why benzocaine precipitate out of the aqueous solution only when the solution is neutralized.
