You're absolutely right! The molecular formula C2H6O can represent two different compounds:

* Ethanol (ethyl alcohol): This is the most common form of alcohol and has the structural formula CH3CH2OH.

* Dimethyl ether: This is an ether and has the structural formula CH3OCH3.

These two compounds have the same molecular formula but different structural formulas. This is a classic example of isomers – molecules with the same molecular formula but different arrangements of atoms.
