Both $(a)$ and $(b)$

Vedclass · Answer

(C) Zwitter ion is a molecule or ion having separate positively and negatively charged groups. Amino acids,which contain both an amino group $(-NH_{2})$ and a carboxylic acid group $(-COOH)$,exist as Zwitter ions at their isoelectric point. Similarly,compounds like sulphanilic acid,which contain an amino group $(-NH_{2})$ and a sulphonic acid group $(-SO_{3}H)$,also exist as Zwitter ions due to the internal transfer of a proton from the acidic group to the basic amino group. Therefore,both combinations can form Zwitter ions.
