Vedclass · Answer

(B) Zwitter ion is a dipolar molecule that contains both a positively charged group and a negatively charged group within the same molecule,resulting in a net charge of zero.Amino acids,such as glycine $(H_2NCH_2COOH)$,contain both a basic amino group $(-NH_2)$ and an acidic carboxylic group $(-COOH)$.In an aqueous solution,the proton from the $-COOH$ group is transferred to the $-NH_2$ group,forming a dipolar ion known as a Zwitter ion: $H_2NCH_2COOH \rightleftharpoons ^+H_3NCH_2COO^-$.Among the given options,only $H_2NCH_2COOH$ is an amino acid capable of forming a Zwitter ion.
