Every Compound can be represented by a formula. There are 3 types of formula:
Empirical Formula –> Simplest whole number ratio of atoms present
Molecular Formula –> Total number of atoms in one molecule
Structural Formula –> Shows how the atoms are linked together in a molecule
Note:
=> Structural Formula DOES NOT give the molecular shape
