C8H8 is the molecular formula for the monomer styrene, which is a colorless, oily liquid with a sweet, floral odor.

Styrene (C8H8) is a versatile monomer used in the production of many different products, including polystyrene, synthetic rubber, and resins. It is a colorless, oily liquid with a sweet, floral odor and is highly soluble in organic solvents.

In the production of polystyrene, styrene is polymerized to produce a hard, thermoplastic polymer that is used in a wide range of products, including packaging materials, disposable cups, and toys. Styrene is also used in the production of synthetic rubber, which is used in various applications such as tires, hoses, and seals.

In addition to its use in the production of polymers, styrene is also used in the production of resins, such as unsaturated polyester resins, which are used in the production of fiberglass-reinforced plastics.

Styrene is a versatile monomer with a wide range of applications. Its ability to polymerize and form hard thermoplastic polymers makes it an essential ingredient in the production of many consumer and industrial products. However, it should be handled with care as it is considered toxic and potentially carcinogenic.
