the acidic group in aqueous solution of glycine is (A) -COOH (B) -COO- (C) -NH2 (D) - textNH text3 text+

Tardigrade Admin · Accepted Answer

In aqueous solution, the α -amino acids form mostly Zwitter ions. NH2CH2COOHleftharpoons H3N+-CH2-COO- If a base is added, H+ ion is furnished by - overset+NH3 . Hence, the acidic group is - overset+NH3 .

Q. the acidic group in aqueous solution of glycine is

$- COO H$

$- CO O^{-}$

$- N H_{2}$

$- NH_{3}^{+}$

In aqueous solution, the $α$ -amino acids form mostly Zwitter ions.

$N H_{2} C H_{2} COO H ⇌ H_{3} N^{+} - C H_{2} - CO O^{-}$

If a base is added, $H^{+}$ ion is furnished by $- N + H_{3}$ . Hence, the acidic group is $- N + H_{3}$ .

Q. the acidic group in aqueous solution of glycine is

−COOH

−COO−

−NH2​

−NH3+​

In aqueous solution, the α -amino acids form mostly Zwitter ions. NH2​CH2​COOH⇌H3​N+−CH2​−COO− If a base is added, H+ ion is furnished by −N+H3​ . Hence, the acidic group is −N+H3​ .

$- COO H$

$- CO O^{-}$

$- N H_{2}$

$- NH_{3}^{+}$

In aqueous solution, the $α$ -amino acids form mostly Zwitter ions.

$N H_{2} C H_{2} COO H ⇌ H_{3} N^{+} - C H_{2} - CO O^{-}$

If a base is added, $H^{+}$ ion is furnished by $- N + H_{3}$ . Hence, the acidic group is $- N + H_{3}$ .
