Zwitter ion is formed when proton goes from:
Correct answer: B. Carboxyl to an amino group
- A. Amino to the carboxyl group
- B. Carboxyl to an amino group
- C. Carboxyl group only
- D. Amino group only
Explanation
Zwitter ion is a dipolar ion which is formed on the combination of a carboxyl group and an amino group. As a result, it is mostly formed by an amino acid. The carboxyl group in a zwitter ion carries a negative charge while the amine group carries a positive charge. There is an internal transfer of a hydrogen ion from the -COOH group to the -NH2 group to leave an ion with both a negative charge and a positive charge. This is called a zwitter ion. This is the form that amino acids exist even in the solid state.

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
