Which of the following compounds can form a Zwitter ion? [NEET 2018]
Text Solution
Verified by ExpertsThe correct answer is:
D
Among the given options, only glycine 
is an amino acid which
contains both acidic (acquiring negative charge) and basic group (acquiring positive charge).
Glycine can form a Zwitter ion because it behaves like salts rather than simple amines or carboxylic acids. In aqueous solution, the carboxyl group can lose a proton and amino group can accept a proton giving rise to a dipolar ion known as Zwitter ion.
