Both assertion and reason are correct but the reason is not correct explanation of the assertion.

Explanation:

A molecule is defined as a substance which can contain atoms of same or different elements that are chemically combined together.

For example, $Cl_{2}$, $O_{2}$, $MgCl_{2}$ etc are molecules.

Whereas a compound is defined as a chemical specie which is made by the combination of different atoms in a fixed ratio by mass.  A compound is a pure substance.
