Compound with molecular formula C3H6O can show : (1) Positional isomerism (2) Both positional isomerism and metamerism (3) Metamerism (4) Functional group isomerism

1. Positional isomerism
2. Both positional isomerism and metamerism
3. Metamerism
4. Functional group isomerism

Correct answer: Positional isomerism

Solution

The compound C3H6O can exhibit positional isomerism because it can have different arrangements of the functional group within the same carbon skeleton, leading to distinct isomers. This type of isomerism occurs when the position of a functional group changes, while the molecular formula remains constant.
