Verified step by step guidance1
Understand the concept of constitutional isomers: Constitutional isomers are compounds that have the same molecular formula but different connectivity of atoms within the molecules.
Identify the molecular formula of the given compound: The molecular formula provided is C3H6O.
Analyze the structure of acetone: Acetone has the molecular formula C3H6O and the structure CH3-CO-CH3, where the carbon atoms are connected in a different order compared to propanal.
Analyze the structure of propanal: Propanal also has the molecular formula C3H6O, but its structure is CH3-CH2-CHO, which is a different connectivity of atoms compared to acetone.
Compare the structures: Since propanal and acetone have the same molecular formula but different connectivity of atoms, they are constitutional isomers of each other.
