The molecular formula of an organic compound represents the number of bonded atoms with their atomic symbols. The structural formula represents all the bonded atoms with chemical bonds and the arrangement of atoms in the molecule. Constitutional isomers can be defined as the pair of molecules with the same molecular formula but different structural formula.
