Explanation:
Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.
Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.
Structural formula is the formula which depicts the actual number of atoms of each element present in the compound by showing the bonding between the atoms.
Lewis structures show the valence electrons around each atom present in the compound.
