\( 2- \) pentanone and \( 3- \) pentanone are:

1. Chain isomers
2. Tautomers
3. Metamers
4. Positional isomers

Correct answer: Positional isomers

Solution

Both compounds have the same molecular formula and the same ketone functional group; only the location of the carbonyl group changes along the pentane chain. That makes them positional isomers.
