melisa1 [442]
<h3><u>Answer;</u></h3>

EtO-PHE-NH2 + H+ _______ EtO-PHE-NH3+ Cl-

<h3><u>Explanation;</u></h3>

  • HCl is used for the acid-base reaction in p-phenetidine in amide synthesis of acetophenetidin rather than water becuase HCl's polarity contributes to a reaction driven to the right. It protonates the amine group, making it easy to dissolve.
