Vedclass · Answer

(B) zwitterion is a molecule that contains an equal number of positively and negatively charged functional groups. In the case of an amino acid,the amino group $(-NH_2)$ acts as a base and accepts a proton to become $-NH_3^+$,while the carboxyl group $(-COOH)$ acts as an acid and loses a proton to become $-COO^-$. This dipolar ion,where the molecule is electrically neutral overall but contains both positive and negative charges,is called a zwitterion. Option $B$ shows the structure $H_3N^+ - CH(R) - COO^-$,which correctly represents this dipolar zwitterionic state.
