It is a component of coal-tar and the US Occupational Health and Safety Administration classifies it as noncarcinogenic. It is quite soluble in carbon disulfide but insoluble in water. Many drugs are hydrophobic, which makes them poorly soluble in water. A naphthalene molecule can be viewed as the fusion of a pair of benzene rings. Alcohol molecules are polar because they contain a hydroxyl (-OH) group. It's a substance found in coal tar. What are two benzene rings together called? This extra resonance makes the phenanthrene around 6 kcal per mol more stable. the Anthraquinone may be formed from direct combustion processes in motor-operated vehicles and engines.
