Article titles for compounds and related topics should reflect how the compound name is commonly written and use Greek letter prefixes if appropriate, e.g. Α-Ketoglutaric acid, using {{DISPLAYTITLE}} to display as α-Ketoglutaric acid, not Alpha-Ketoglutaric acid and displaying as alpha-Ketoglutaric acid.
Cycloalkanes and aromatic compounds can be treated as the main parent chain of the compound, in which case the positions of substituents are numbered around the ring structure. For example, the three isomers of xylene CH 3 C 6 H 4 CH 3 , commonly the ortho- , meta- , and para- forms, are 1,2-dimethylbenzene, 1,3-dimethylbenzene, and 1,4 ...
For the compound, SnO 2, the tin ion is Sn 4+ (balancing out the 4− charge on the two O 2− anions), and because this is a higher oxidation state than the alternative (Sn 2+), this compound is termed stannic oxide. Some ionic compounds contain polyatomic ions, which are charged entities containing two or more covalently bonded types of atoms ...
Hydrates are ionic compounds that have absorbed water. They are named as the ionic compound followed by a numerical prefix and -hydrate. The numerical prefixes used are listed below (see IUPAC numerical multiplier): mono-di-tri-tetra-penta-hexa-hepta-octa-nona-deca-For example, CuSO 4 ·5H 2 O is "copper(II) sulfate pentahydrate".
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
Numerical terms for compound or complex features [ edit ] Numerical prefixes for multiplication of compound or complex (as in complicated ) features are created by adding kis to the basic numerical prefix, with the exception of numbers 2 and 3, which are bis- and tris-, respectively.
For organometallic compounds of groups 1–2 can use additive (indicating a molecular aggregate) or compositional naming. Examples are: [BeEtH] named ethylhydridoberyllium or ethanidohydridoberyllium [Mg(η 5-C 5 H 5) 2] named bis(η 5-cyclopentadienyl)magnesium, or bis(η 5-cyclopentadienido)magnesium; Na(CHCH 2) sodium ethenide (compositional ...
For example, the sodium benzoate is an ionic compound with the structure C 6 H 5 –CO–O − Na +, and its condensed structural formula usually written as C 6 H 5 CO 2 Na. The suffix comes from "-oic acid". The most common examples of compounds named with the "oate" suffix are esters, like ethyl acetate, CH 3 COOCH 2 CH 3.
