Answer:
Structural formula
Explanation:
Various type of formulae describe an organic compound. The empirical formula only shows the ratio of atoms of each element present. The molecular formula shows the exact number of atoms of each element present.
Lastly, the structural formula shows us the arrangement of these atoms in space. It shows us the number of atoms, nature and bond types in organic compounds.
The structural formula enables us to picture what the real molecule must look like.
