A chemical formula that indicates the relative proportions of the elements in a molecule rather than the actual number of atoms of the elements. The empirical formula of a compound may be simpler than its molecular formula, which is a multiple of the empirical formula. For example, glucose has the molecular formula C6 H12 O6 but the empirical formula CH2 O.
A chemical formula that shows how the atoms making up a compound are arranged within the molecule. For example, the structural formula of aspirin is CH3 COOC6 H4 COOH, indicating that it consists of an acetyl group (CH3 COO) attached to the carboxylic acid (COOH) of a phenyl group (C6 H4 ).
