Why is the molecular formula of benzene written as C6H6?

The molecular formula of benzene is written as C₆H₆ because it reflects the actual number of carbon and hydrogen atoms in a benzene molecule. Benzene has a unique structure where six carbon atoms form a ring, and each carbon is bonded to one hydrogen atom. This specific arrangement gives benzene its characteristic stability and properties, which are important in organic chemistry. The formula also indicates that benzene is an unsaturated hydrocarbon, as it follows the general formula for aromatic hydrocarbons.
