Vedclass · Answer

(A) Amino acids are amphoteric in nature. In an acidic medium (low $pH$),the amino group $(-NH_2)$ gets protonated to form $-NH_3^+$.Thus,at $pH = 2$,the structure $A$ is $H_3N^+-CH(CH(CH_3)_2)-COOH$.In a basic medium (high $pH$),the carboxylic acid group $(-COOH)$ gets deprotonated to form $-COO^-$.Thus,at $pH = 10$,the structure $B$ is $H_2N-CH(CH(CH_3)_2)-COO^-$.Therefore,the correct option is $A$.
