BENZENE: Benzene is an important organic chemical compound with the chemical formula C6H6. It’s molecules is composed of (6) carbon atoms joined in ring, with (1) hydrogen atom attached to each carbon atom. Benzene it’s molecules contain only hydrocarbon. Benzene is an aromatic hydrocarbon and a cyclic hydrocarbon with a continuous pi bond. Benzene it has a high octane number.

AROMATIC COMPOUNDS: Aromatic compounds are more stable than we might expect when we see a structure showing single and double bonds. It is common to stat by saying that aromatic compounds are compounds related to benzene. Defining aromatic in terms of benzene is a useful start in an introductory course. As we will see here, it is not easy to give a more complete definition that is satisfying in an introductory course. For example one simple is pyridine C5H5N shows below

Pyridine is very similar to benzene High performance liquid chromatography: HPLC HPLC, formerly referred to as high pressure liquid Chromatography is a technique in analytical chemistry used to separate, identify, and quantify each component in a mixture. It relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid absorbent material. HPLC has been used for medical for example detecting Vitamin D levels in blood serum, legal (e.g) detecting performance enhancement drugs in urine.
