Vedclass · Answer

(B) In aqueous solution,the carboxyl group of an amino acid can lose a proton and the amino group can accept a proton,giving rise to a dipolar ion known as a zwitterion. Thus,Assertion $(A)$ is true.Most naturally occurring amino acids have the $L$-configuration,where the $-NH_2$ group is on the left side in the Fischer projection. Thus,Reason $(R)$ is true.However,the $L$-configuration of amino acids is not the reason why they exist as dipolar ions in aqueous solution. The dipolar nature is due to the acid-base properties of the functional groups present. Therefore,$(R)$ is not the correct explanation for $(A)$.

Assertion $(A)$: In aqueous solution,amino acids exist in dipolar ion form.
Reason $(R)$: Most of the naturally occurring amino acids have $L$-configuration.
The correct option among the following is:
