In amino acid proton is transferred from one point to the other point and this dipolar ion is called:
Correct answer: C. Zwitter ion
- A. Oxonium ion
- B. Carbonium ion
- C. Zwitter ion
- D. Carbanion
Explanation
Zwitterion is correct because in an amino acid, the proton is transferred from the carboxyl group (-COOH) to the amino group (-NH2), resulting in the formation of a dipolar ion where the amino group becomes positively charged (NH3+) and the carboxyl group becomes negatively charged (COO-). This dipolar ion is known as a zwitterion.

About Carboxylic Acids
Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
