Empirical Formulae of Compounds with Molecular Formulae
Empirical formula is the simplest whole number ratio of atoms in a compound. It is obtained by dividing the molecular formula by the greatest common factor of its subscripts. Here are some examples of how to determine the empirical formula of a compound based on its molecular formula.
Example 1: C6H12O6 (glucose)
Step 1: Find the greatest common factor of the subscripts: 6.
Step 2: Divide each subscript by the greatest common factor: C1H2O1.
Step 3: The empirical formula is CH2O.
Example 2: C8H18 (octane)
Step 1: Find the greatest common factor of the subscripts: 2.
Step 2: Divide each subscript by the greatest common factor: C4H9.
Step 3: The empirical formula is C4H9.
Example 3: C2H5OH (ethanol)
Step 1: Find the greatest common factor of the subscripts: 1.
Step 2: Divide each subscript by the greatest common factor: C2H6O.
Step 3: The empirical formula is C2H6O.
Example 4: C6H6 (benzene)
Step 1: Find the greatest common factor of the subscripts: 6.
Step 2: Divide each subscript by the greatest common factor: CH.
Step 3: The empirical formula is CH.
Example 5: C12H22O11 (sucrose)
Step 1: Find the greatest common factor of the subscripts: 2.
Step 2: Divide each subscript by the greatest common factor: C6H11O5.
Step 3: The empirical formula is C6H11O5.
Conclusion
Empirical formula is the simplest whole number ratio of atoms in a compound. It can be determined by dividing the molecular formula by the greatest common factor of its subscripts. Knowing the empirical formula is important in determining the molecular formula and the chemical properties of a compound.
