Which of the following shows tautomerism?
Correct answer: A. Amino acids
- A. Amino acids
- B. Amines
- C. Carboxylic acids
- D. All of these
Explanation
Tautomerism is a form of isomerism involving the migration of a proton. The most common type, keto-enol tautomerism, requires the presence of a hydrogen atom on a carbon adjacent (alpha) to a carbonyl group.

About Isomerism
Isomerism occurs when compounds have the same molecular formula but different atom arrangements or spatial orientations. The content includes chain, position, functional, metameric and tautomeric isomerism, along with geometrical and optical isomerism, including cis-trans forms, E/Z notation, chirality and enantiomers.
