Correct answer: C. Internal Salt
- A. Cation
- B. Neutral Amino Acid
- C. Internal Salt
- D. Anion
Explanation
There is an internal transfer of a hydrogen ion from the COOH group to the NH2 group, leaving an ion with both a negative charge and a positive charge. This is called a zwitterion, or internal salt. The term internal salt refers to the dipolar character of amino acids.

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.
