Question
In a highly alkaline aqueous medium (pH $\approx$ 12), the neutral zwitterion form of an $\alpha$ -amino acid will predominantly convert into a(n):
Answer: B
π‘ Solution & Explanation
At high pH (alkaline medium), the zwitterion loses a proton from its $-NH_3^+$ group to become $-NH_2$. Because the carboxyl group remains as $-COO^-$, the entire molecule carries a net negative charge (anion).
