In the formation of Zwitterions, proton goes from
Correct answer: A. Carboxyl to amino group
- A. Carboxyl to amino group
- B. Amino to carboxyl group
- C. Amino group only
- D. Carboxyl group only
Explanation
In the formation of a zwitterion, a proton shifts from the carboxylic acid group (-COOH) to the amino group (-NH₂) within the amino acid molecule. This internal transfer results in:Positive charge on the amino group: The nitrogen atom gains the proton, acquiring a positive formal charge (NH₃⁺).Negative charge on the carboxylate group: The oxygen atom of the carboxylic acid loses the proton, becoming negatively charged (COO⁻).This internal ionic structure, with opposite charges within the molecule, characterizes 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.
