Acetaldehyde and Vinyl alcohol show _
Correct answer: D. Tautomerism
- A. Stereoisomerism
- B. Metamerism
- C. Positional isomerism
- D. Tautomerism
Explanation
The correct answer is Tautomerism. Acetaldehyde and vinyl alcohol are examples of tautomers, which are isomers that can readily interconvert by the shift of a hydrogen atom and a double bond. In this case, acetaldehyde (CH3CHO) can convert to vinyl alcohol (C2H4O) through this tautomeric process. Tautomerism is characterized by the rapid equilibrium between these forms, unlike other types of isomerism.On the other hand, the other options are incorrect for the following reasons:Stereoisomerism describes isomers that differ in the spatial arrangement of atoms but have the same connectivity. Acetaldehyde and vinyl alcohol do not merely differ in 3D arrangement.Metamerism arises when there is an unequal distribution of carbon atoms around a functional group, which is not the case here.Positional isomerism involves variations in the position of the same functional group within the same carbon skeleton, which does not apply to these two compounds.

About Fundamental Principles of Organic Chemistry
Organic chemistry begins with carbon compounds classified by carbon skeleton, saturation and functional group. Work includes identifying groups such as hydroxyl, carbonyl, carboxyl and amino, applying basic nomenclature, and distinguishing structural, geometric and optical isomers, where the same molecular formula does not necessarily mean the same structure or properties.
