Different covalent compounds can have not only the same empirical formula but also the same molecular formula. For example, C2H6O can be either dimethyl ether or ethanol. This can occur because of differences in bonding patterns. In dimethyl ether, the oxygen atom is bonded directly to both carbon atoms, but in ethanol the oxygen atom is bonded to oxygen and hydrogen instead.

Formulas
The concept of empirical formulas apply to ionic compounds. You write the action first, the anion second, and use the minimal amount of atoms possible to make a neutral compound. A molecular formula would be the formula without necessarily the minimum amount of atoms.
Molecular formulas are used the most often, but empirical formulas do help at times. Often it's just to simplify the molecular formula, but this simplification can often tell you if it's in the same chemical family as other compounds and such.

Two compounds that have the same molecular formula but different structural formulas are isomers of each other.
Because unlike the empirical formula, the molecular formula does not have to be the simplest ratio.If by chance you are given the percent composition of the elements in a substance, you could calculate the empirical formula and then the empirical formula's mass. However, the molecular formula equation is molecular formula= (empirical formula)n, where n is the mass of the molecular formula divided by the mass of the empirical formula. You would, therefore, need to know the mass belonging to the molecular formula, which you are not given.
These compounds are called insecticides and have very different formulas.
C6H12O6 is an empirical formula.
A molecular formula is identical to the empirical formula, and is based on quantity of atoms of each type in the compound.The relationship between empirical and molecular formula is that the empirical formula is the simplest formula, and the molecular can be the same as the empirical, or some multiple of it. An example might be an empirical formula of C3H8. Its molecular formula may be C3H8 , C6H16, C9H24, etc. Looking at it the other way, if the molecular formula is C6H12O6, the empirical formula would be CH2O.
