The potential energy possessed by a molecule is dependent upon

Its composition and structure

Explanation:

The potential energy possessed by a molecule depends on its composition and structure. Its composition determines the type of intramolecular bonds present in the molecule and its structure determines the strength of the intramolecular bonds. Let's look at the example of the water molecule. It consists of two hydrogen atoms and one oxygen atom. The intramolecular bonds present here is the covalent O-H bond and since it has two O-H bonds in a molecule, and is V-shaped. These two properties determine the magnitude of the potential energy of the molecule.
