Specifically, the colour of a halogen, such as chlorine, results from the electron transition between the highest occupied antibonding π g molecular orbital and the lowest vacant antibonding σ u molecular orbital. [40] The colour fades at low temperatures, so that solid chlorine at −195 °C is almost colourless. [39]
Values can be higher than 100% because hypochlorite ion has a molecular weight of 51.45 g/mol, whereas dichlorine Cl 2 has a molecular weight of 70.90 g/mol. Dichlorine has a reference bleaching potential of 100% for its molecular weight. Hypochlorite (ClO) also has a molecule-to-molecule bleaching potential the same as dichlorine.
Dichlorine monoxide is an inorganic compound with the molecular formula Cl 2 O. It was first synthesised in 1834 by Antoine Jérôme Balard, [2] who along with Gay-Lussac also determined its composition. In older literature it is often referred to as chlorine monoxide, [3] which can be a source of confusion as that name now refers to the ClO ...
Chloromethane, also called methyl chloride, Refrigerant-40, R-40 or HCC 40, is an organic compound with the chemical formula CH 3 Cl.One of the haloalkanes, it is a colorless, sweet-smelling, flammable gas.
In chemistry, equivalent weight (also known as gram equivalent [1] or equivalent mass) is the mass of one equivalent, that is the mass of a given substance which will combine with or displace a fixed quantity of another substance.
Copper at red heat (300-400°C) combines directly with chlorine gas, giving (molten) copper(II) chloride. The reaction is very exothermic. [8] [15] Cu(s) + Cl 2 (g) → CuCl 2 (l) A solution of copper(II) chloride is commercially produced by adding chlorine gas to a circulating mixture of hydrochloric acid and copper. From this solution, the ...
This seen in the ferrocene-related product of the following reaction: SnCl 2 + Fe(η 5-C 5 H 5)(CO) 2 HgCl → Fe(η 5-C 5 H 5)(CO) 2 SnCl 3 + Hg. SnCl 2 can be used to make a variety of such compounds containing metal-metal bonds. For example, the reaction with dicobalt octacarbonyl: SnCl 2 + Co 2 (CO) 8 → (CO) 4 Co-(SnCl 2)-Co(CO) 4
Molecular weight (M.W.) (for molecular compounds) and formula weight (F.W.) (for non-molecular compounds), are older terms for what is now more correctly called the relative molar mass (M r). [8] This is a dimensionless quantity (i.e., a pure number, without units) equal to the molar mass divided by the molar mass constant .
