Which of the following compounds can form a zwitter ion?

Aniline

Acetanilide

Glycine

Benzoic acid

Solution

Glycine

Amphoteric Nature of Glycine: In aqueous solution, glycine exists as an inner salt or a dipolar ion.
$H_{2} {NCH}_{2} COOH + H_{2} O ⇌ H_{3} N^{+} {CH}_{2} {COO}^{-} + H_{2} O$

This doubly charged ion is known as a Zwitterion or an ampholyte. Due to formation of the ampholyte, glycine acts both as an acid or a base.

In aqueous solution, Zwitter- ion tends to lose a proton. Hence, if electrolyzed, the negative glycine ion will migrate to anode.
$H_{3} N^{+} {CH}_{2} {COO}^{-} + H_{2} O ⇌ [{NH}_{2} {CH}_{2} {COO}^{-}] + H_{3} O^{+}$

The pH value for the isoelectric point of glycine is 6.0.
