Relation Between Empirical and Molecular Formulae
Relation Between Empirical and Molecular Formulae
The empirical formula of a compound gives the simplest whole-number ratio of the atoms of the elements present in a molecule of the compound. For example, the empirical formula of benzene is CH, while that of hydrogen peroxide
is HO. The empirical formula does not represent the actual formula of the compound
Molecular or chemical formula: A molecular formula is a representation of a chemical compound using a set of symbols for the atoms of elements present in a molecule of the compound, and shows the actual number of atoms of each element of the compound. In some cases, empirical and molecular formulas are same, e.g., methane , boron trichloride
, etc.
