Chlorine Oxides Chlorine and oxygen also can bond in numerousways:· chlorine monoxide, ClO2,chlorine(II) oxide· chlorine dioxide, ClO,chlorine(IV) oxide· chloroperoxyl, ClOO· chlorine trioxide, ClO3,chlorine(VI) oxide· dichlorine monoxide, Cl2O, chlorine(I) oxide3 dichlorine dioxides: ClO dimer, Cl2O2, chlorine peroxide chloryl chloride, ClO2Cl, chlorine(0,IV) oxide chlorine chlorite, ClOClO, chlorine(I,III) oxide Chlorine Peroxide Names IUPAC name Dichlorine dioxide Other names Chlorine(I) oxide; ClO dimer Identifiers CAS Number · 12292-23-8 3D model · Interactive image ChemSpider · 109895 PubChem CID · 123287 InChI SMILES Properties Chemical formula Cl2O2 Molar mass 102.905 g/mol Excluding where else noted, data are given for materials in their standard state (at 25 °C 77 °F 100 kPa). Chlorine peroxide (alsoidentified as dichlorine dioxide or dimer) is a molecularcompound with method ClOOCl. Chemically,this is a dimer ofthe chlorine monoxide radical (ClO). It is dynamic inthe development of the ozone hole. Chlorine peroxide catalytically changes ozone into oxygen when it is visibleby infrared light.DimerA dimeris an oligomer containing oftwo fundamentally similar monomers joined by bondsthat can be each strong or weak, covalent and intermolecular. The term homo dimer is used when the twomolecules are similar and hetero dimer whenthey are not.
The inverse of dimerisation is normally called dissociation. When two oppositely charged ions companion into dimers,they are stated to as Bjerrum sets.Ozone HoleOzone depletion defines two connected phenomena observed since the late1970.
A steady failure of about four percent in the tot al amount of ozone in Earth’s stratosphere and a much larger springtidediminution in stratospheric ozone around Earth’s freezing regions. Thelatter phenomenon is referred to as the ozone hole. There are also spring time polar tropospheric ozonedepletion events in adding to these stratospheric phenomena. ProductionChlorine peroxide can be produced by laser or infrared photolysis of thechlorine molecule with ozone. The lasers used to break up the chlorinemolecule into atoms can be an excimerlaser at 248, 308, or 352 nm wavelength. Difluorodichloromethane (CF2Cl2)can also act as a source of chlorine atoms for the formation of theperoxide.
Microwave expulsion can also break up chlorine molecules intoatoms that react with ozone to style chlorine peroxide. ChemicalReactions Cl2 + hv ? 2Cl Cl + O3 ? O2 + ClO 2ClO + M ?

Cl + O2Dichlorodifluoromethane is a neutral gas usually sold under the brand name Freon-12, and a chlorofluorocarbonhalomethane (CFC) used as a refrigerant and aerosol spray propellant. Complying with the Montreal Protocol, its making was banned indeveloped countries in 1996, and rising countries in 2010 due to concerns aboutits damaging impact to the ozone layer.
Its only allowed usage is asfire retardant in submarines and aircraft. It is solvable in many organic diluters.Dichlorodifluoromethane was one of the unique propellants for Silly String. R-12 cylinders are having white color.Excimer LaserAn excimer laser, sometimes morecorrectly called an exciplex laser,is a form of ultraviolet laser which is normally help in the production of microelectronic devices, semiconductor built integrated circuits or “chips”, eye surgery, and micro machining. PropertiesChlorine peroxide rivets ultraviolet light with a maximum absorbingwavelength of 245 nm.
It also engages longer wavelengths up to 350 nmto a lesser extent. This is important as ozone grips up to 300 nm. The Cl?O bond length is 1.704 Å, and the O?O bond is 1.426 Ålong.
The ClOO bond angle is 110.1, and the dihedralangle amongst the two Cl?O?O planes is 81Dihedral AngleA dihedralangle is the angle between two crossing planes. In chemistry it is the anglebetween planes through two sets of three atoms, having two atoms in common.In solid geometry it is definiteas the union of a line and two half-planes that have thisline as a common edge. In advanceddimension, a dihedral angle signifies the angle among two hyper planes.
