Empirical formulas are the simplest form of notation. They provide the lowest whole-number ratio between the elements in a compound. For butane and isobutane, the empirical formula for both molecules is C2H5, and they share the same molecular formula, C4H10.An empirical formula lists the elements of a compound but not the structure. Oxalic acid has the formula C2H2O4. Its structure is HOOC-COOH. Multiple compounds can have the same empirical formula and a different structure.
