WebBenzocaine is not soluble in water (unlike its conjugate acid) and therefore will precipitate out as a white solid 2) If NaOH is used instead of HCl in the extraction step, benzocaine will not form its conjugate acid and hence will remain as benzocaine and therefore will get extracted in the organic fraction. WebFeb 13, 2024 · Benzocaine has a free amine group and so can be protonated with HCl. I can't draw the structure here but let R be the main group (benzene ring with an ester), and it has the free NH2 on it also. R-NH2 + HCl ===> RNH3+ + Cl- This hydrochloride salt will be more soluble in water than in ether. Upvote • 0 Downvote Add comment Report
