In a chemical change, the molecular structure of the substance changes.

Explanation:

Chemical change is the change in which chemical composition of the substance changes by rearrangement of atoms. The molecular structure changes due to change in atoms.

Example:

Physical change is a change in which only the physical properties such as size, shape etc change and there is no rearrangement of atoms.
