Vedclass · Answer

(A) $\alpha$-amino acids contain both an acidic carboxyl group $(-COOH)$ and a basic amino group $(-NH_2)$.In aqueous solution,the carboxyl group loses a proton $(H^{+})$ and the amino group accepts it,forming a dipolar ion known as a zwitterion or internal salt: $NH_2-CHR-COOH \rightleftharpoons NH_3^+-CHR-COO^-$.This occurs because the acidic and basic groups are in close proximity.Therefore,both Assertion and Reason are correct,and the Reason is the correct explanation.

Assertion: $\alpha$-amino acids exist as internal salt in solution as they have amino and carboxylic acid groups in near vicinity.
Reason: $H^{+}$ ion given by carboxylic group $(-COOH)$ is captured by amino group $(-NH_2)$ having lone pair of electrons.
