Answer
Isomers with different structures but same molecular formulas.
Properties of structural isomers are different as they have different structures.
Work Step by Step
Structural isomers are molecules whose structures are different but molecular formulas are same.
Properties of structural isomers differ from one another due to their structural differences. These structural differences make these isomers different compounds. As a result, the melting points, boiling points and other physical properties of these isomers are different.
