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).
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.
It is used as a solid substitute for phosgene, which is a gas and diphosgene, which is a liquid. [ 5 ] [ 6 ] Triphosgene is stable up to 200 °C. [ 7 ] Triphosgene is used in a variety of halogenation reactions.
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 ...
Crystalline benzoic acid shown here is a solid and an acid, but, in the context of this article, it is not a "solid acid", which are polymeric materials and typically stronger acids. Examples of inorganic solid acids include silico-aluminates ( zeolites , alumina , silico-aluminophosphate), and sulfated zirconia .
Azoth – initially this referred to a supposed universal solvent but later became another name for Mercury. Bitumen – highly viscous liquid or semi-solid form of petroleum. Blende; Brimstone – sulfur; Flowers of sulfur – formed by distilling sulfur. Caustic potash/caustic wood alkali – potassium hydroxide, formed by adding lime to potash.
See: E-Z notation Violet leaf aldehyde, systematic name (E,Z)-nona-2,6-dienal, is a compound having one (E)- and one (Z)-configured double bond. The descriptors (E) (from German entgegen, 'opposite') and (Z) (from German zusammen, 'together') are used to provide a distinct description of the substitution pattern for alkenes, cumulenes or other double bond systems such as oximes.
An organic acid is an organic compound with acidic properties. The most common organic acids are the carboxylic acids , whose acidity is associated with their carboxyl group –COOH. Sulfonic acids , containing the group –SO 2 OH, are relatively stronger acids.
