Final answer:
While there is no common substance named Benzoin Rosin, benzene is an aromatic hydrocarbon known for its industrial uses, carcinogenic properties, and restricted usage in consumer products.
Step-by-step explanation:
The substance "Benzoin Rosin" appears to be a misunderstanding or mistake, as there is no common chemical substance by that name. You may mean either "benzoin," a crystalline compound used in organic synthesis and as a medication, or "rosin," derived from pine sap and used in varnishes and adhesives. However, it is possible to discuss benzene, a related aromatic compound, which is the simplest member of the large family of hydrocarbons known as aromatic hydrocarbons. Benzene is a liquid with a gasoline-like smell, boils at 80°C, and freezes at 5.5°C. The aromatic structure of benzene, C6H6, consists of a ring where the pi bonding electrons are free to move completely around the ring, showing delocalization which is best described using the resonance hybrid concept of valence bond theory or molecular orbital theory. Benzene is an important industrial precursor used in the production of a wide array of products, including plastics, drugs, detergents, synthetic rubber, pesticides, and dyes. Due to its carcinogenic properties, the use of benzene in consumer products and as a gasoline additive has been restricted.
