Anhydrous cobalt(II) fluoride. Cobalt(II) fluoride is a chemical compound with the formula (CoF 2).It is a pink crystalline solid compound [1] [2] which is antiferromagnetic at low temperatures (T N =37.7 K) [3] The formula is given for both the red tetragonal crystal, (CoF 2), and the tetrahydrate red orthogonal crystal, (CoF 2 ·4H 2 O).
Cobalt(II) nitrate exists in the anhydrous form and the hydrate form, of which the hexahydrate is the most common. Cobalt nitrate hexahydrate (Co(NO 3 ) 2 ·6H 2 O) is a red deliquescence crystal that is easily soluble in water, [ 12 ] and its molecule contains cobalt(II) hydrated ions ([Co(H 2 O) 6 ] 2+ ) and free nitrate ions.

Carbonyl fluoride is usually produced as a decomposition product of fluorinated hydrocarbons in the thermal decomposition thereof, for example from trifluoromethanol or tetrafluoromethane in the presence of water:
The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks. The suffix -ol appears in the International Union of Pure and Applied Chemistry (IUPAC) chemical name of all substances where the hydroxyl group is the functional group with the ...
Where an acid has both a systematic and a common name (like CH 3 COOH, for example, which is known as both acetic acid and as ethanoic acid), its salts can be named from either parent name. Thus, KCH 3 CO 2 can be named as potassium acetate or as potassium ethanoate.
The systematic IUPAC name is not always the preferred IUPAC name, for example, lactic acid is a common, and also the preferred, name for what systematic rules call 2-hydroxypropanoic acid. This list is ordered by the number of carbon atoms in a carboxylic acid.
