Cyclohexane is a cycloalkane with the molecular formula C 6 H 12. Cyclohexane is non-polar . Cyclohexane is a colourless, flammable liquid with a distinctive detergent -like odor, reminiscent of cleaning products (in which it is sometimes used).
Glucose (C 6 H 12 O 6), ribose (C 5 H 10 O 5), Acetic acid (C 2 H 4 O 2), and formaldehyde (CH 2 O) all have different molecular formulas but the same empirical formula: CH 2 O.This is the actual molecular formula for formaldehyde, but acetic acid has double the number of atoms, ribose has five times the number of atoms, and glucose has six times the number of atoms.

Starting from the idealized material tungsten trioxide, one can generate a series of related materials that are slightly deficient in oxygen. These oxygen-deficient species can be described as WO 3− x , but in fact they are stoichiometric species with large unit cells with the formulas W n O 3 n −2 , where n = 20, 24, 25, 40.
The rest of the Earth's crust is formed also of oxygen compounds, most importantly calcium carbonate (in limestone) and silicates (in feldspars). Water-soluble silicates in the form of Na 4 SiO 4, Na 2 SiO 3, and Na 2 Si 2 O 5 are used as detergents and adhesives. [6] Peroxides retain some of oxygen's original molecular structure ((− O-O −).
Cyanogen is the chemical compound with the formula (C N) 2. The simplest stable carbon nitride, it is a colorless and highly toxic gas with a pungent odor. The molecule is a pseudohalogen. Cyanogen molecules consist of two CN groups ‒ analogous to diatomic halogen molecules, such as Cl 2, but far less oxidizing.
Cyclohexanol is produced by the oxidation of cyclohexane in air, typically using cobalt catalysts: [5]. 2 C 6 H 12 + O 2 → 2 C 6 H 11 OH. This process coforms cyclohexanone, and this mixture ("KA oil" for ketone-alcohol oil) is the main feedstock for the production of adipic acid.
Of the two half reactions, the oxidation step is the most demanding because it requires the coupling of 4 electron and proton transfers and the formation of an oxygen-oxygen bond. This process occurs naturally in plants photosystem II to provide protons and electrons for the photosynthesis process and release oxygen to the atmosphere, [ 1 ] as ...
