The premier example is of the class is Mo 6 Cl 14 2−. This dianion is available as a variety of salts by treating the polymer molybdenum(II) chloride with sources of chloride, even hydrochloric acid. A related example is W 6 Cl 14 2− anion, which is obtained by extraction of tungsten(II) chloride. Structure of [M 6 Cl 14] 2− (M = Mo or W).
1,1-Dichloroethylene, commonly called vinylidene chloride or 1,1-DCE, is an organochloride with the molecular formula CCl 2 CH 2.It is a colorless liquid with a sharp odor. Like most chlorocarbons, it is poorly soluble in water but soluble in organic solvents. 1,1-DCE was the precursor to the original clingwrap, Saran, for food, but this application has been phased
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
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.
This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately.
Examples of Cu(II)-thioether complexes were prepared from 14-ane-S4 [13] and 15-ane-S5. [11] The hexadentate ligand 18-ane-6 also forms extensive family of complexes, including unusual examples of Pd(III) and Ag(II). [14] Examples of homoleptic complexes [M(SR 2) 6] n+ are otherwise rare.
HCCo 3 (CO) 9, a metal cluster complex with a methylidyne ligand.. As an odd-electron species, CH is a radical. The ground state is a doublet (X 2 Π).The first two excited states are a quartet (with three unpaired electrons) (a 4 Σ −) and a doublet (A 2 Δ).
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.
