[1] [2] [3] Introduced by Gilbert N. Lewis in his 1916 article The Atom and the Molecule, a Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds. [4] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.
Chlorine is a toxic gas that attacks the respiratory system, eyes, and skin. [126] Because it is denser than air, it tends to accumulate at the bottom of poorly ventilated spaces. Chlorine gas is a strong oxidizer, which may react with flammable materials. [127] [128]
Phosgene is an organic chemical compound with the formula COCl 2.It is a toxic, colorless gas; in low concentrations, its musty odor resembles that of freshly cut hay or grass. [7]
Chlorine dioxide is a chemical compound with the formula ClO 2 that exists as yellowish-green gas above 11 °C, a reddish-brown liquid between 11 °C and −59 °C, and as bright orange crystals below −59 °C. It is usually handled as an aqueous solution.
The earliest method of synthesis was to treat mercury(II) oxide with chlorine gas. [3] However, this method is expensive, as well as highly dangerous due to the risk of mercury poisoning. 2 Cl 2 + HgO → HgCl 2 + Cl 2 O. A safer and more convenient method of production is the reaction of chlorine gas with hydrated sodium carbonate at 20–30 ...

Chlorine monofluoride is a volatile interhalogen compound with the chemical formula ClF. It is a colourless gas at room temperature and is stable even at high temperatures. When cooled to −100 °C, ClF condenses as a pale yellow liquid. Many of its properties are intermediate between its parent halogens, Cl 2 and F 2. [1]
Chlorine nitrate, with chemical formula ClONO 2 is an important atmospheric gas present in the stratosphere. It is an important sink of reactive chlorine and nitrogen, and thus its formation and destruction play an important role in the depletion of ozone.
