This lists the character tables for the more common molecular point groups used in the study of molecular symmetry. These tables are based on the group-theoretical treatment of the symmetry operations present in common molecules, and are useful in molecular spectroscopy and quantum chemistry. Information regarding the use of the tables, as well ...
The name "homologous series" is also often used for any collection of compounds that have similar structures or include the same functional group, such as the general alkanes (straight and branched), the alkenes (olefins), the carbohydrates, etc. However, if the members cannot be arranged in a linear order by a single parameter, the collection ...
The irreducible complex characters of a finite group form a character table which encodes much useful information about the group G in a concise form. Each row is labelled by an irreducible character and the entries in the row are the values of that character on any representative of the respective conjugacy class of G (because characters are class functions).
Methine or methylylidene (IUPAC) In organic chemistry, a methine group or methine bridge is a trivalent functional group =CH−, derived formally from methane.It consists of a carbon atom bound by two single bonds and one double bond, where one of the single bonds is to a hydrogen.
Propylene, also known as propene, is an unsaturated organic compound with the chemical formula CH 3 CH=CH 2.It has one double bond, and is the second simplest member of the alkene class of hydrocarbons.
In organic chemistry, methenium (also called methylium, carbenium, [2] methyl cation, or protonated methylene) is a cation with the formula CH + 3.It can be viewed as a methylene radical (: CH
The main purpose of chemical nomenclature is to disambiguate the spoken or written names of chemical compounds: each name should refer to one compound. Secondarily, each compound should have only one name, although in some cases some alternative names are accepted. Preferably, the name should also represent the structure or chemistry of a compound.
Tebbe's reagent is the organometallic compound with the formula (C 5 H 5) 2 TiCH 2 ClAl(CH 3) 2.It is used in the methylidenation of carbonyl compounds, that is it converts organic compounds containing the R 2 C=O group into the related R 2 C=CH 2 derivative. [1]
