The structural formula is a chemical composition that represents the arrangement and binding mode of atoms in a compound (or a single substance) by means of elemental symbols and short lines. Is a simple description of the molecular structure.

 

Molecular formula is a chemical formula that represents the composition and relative molecular weight of a substance (a simple substance or a compound) by means of elemental symbols

 

The molecular formula is different from the most simplified formula. For the compound, their molecular formula is an integer multiple of the most simplified formula, or the relative molecular mass is the integer multiple of the most simplified quantity. The simplest formula is the same as the molecular formula only when the relative molecular mass is the same as the most simplified quantity.

 

When the molecular formula is the same, it is also possible that they are not a substance, they may be isomers.
