The video tutorial explains various types of formulas used to represent organic molecules, including displayed, structural, molecular, and empirical formulas. Displayed formulas provide a clear visual structure, while structural formulas simplify common molecules by omitting known bonds. Molecular formulas indicate the number of each atom type but not their arrangement. Empirical formulas show the simplest whole number ratio of atoms. Examples like butene, butanoic acid, propane, pentane, hexane, and glucose illustrate these concepts.
