Acetonitrile is the chemical compound with the formula CH3CN. This colourless liquid is the simplest organic nitrile (hydrogen cyanide is a simpler nitrile, but the cyanide anion is not classed as organic). It is produced mainly as a byproduct of acrylonitrile manufacture. It is used as a polar aprotic solvent in organic synthesis and in the purification of butadiene.
Cubic green crystals that are insoluble in water but soluble in acids. Manganese dioxide is the inorganic compound with the formula MnO2. This blackish or brown solid occurs naturally as the mineral pyrolusite, which is the main ore of manganese.
Cyclohexanone (also known as Oxocyclohexane, pimelic ketone, cyclohexyl ketone, and CYC) is a clear oily liquid that has a colourless to light yellow tinge and a pungent odour. It has the formula C6H10O and is slightly soluble in water and is completely miscible with common solvents. It occurs naturally in crude oils and is also produced synthetically, in large quantities, as it is a key intermediate in the production of nylon.
Pyridine is a basic heterocyclic organic compound with the chemical formula C5H5N. It is structurally related to benzene, with one methine group (=CH−) replaced by a nitrogen atom. The pyridine ring occurs in many important compounds, including azines and the vitamins niacin and pyridoxine.
