The dot-and-cross diagram for molecular oxygen in the ground state. The oxygen nuclei are as indicated and the electrons are denoted by either dots or crosses, depending on their relative spins. The above three-dimensional LDQ structures are useful for visualising the molecular structures, but they can be laborious to construct.
Chlorine dioxide is approximately 10 times more soluble in water than elemental chlorine [1] but its solubility is very temperature-dependent. At partial pressures above 10 kPa (1.5 psi) [ 1 ] (or gas-phase concentrations greater than 10% volume in air at STP ) of ClO 2 may explosively decompose into chlorine and oxygen .
English: Chlorine_dioxide.png new as SVG and with angle/bondlength. Note: This is more or less the structure given by Pauling on page 264 of his General Chemisty, although he puts three dots between the left-hand oxygen and the chlorine, as well as a line segment, instead of two line segments and a dot on the chlorine as we have here.
[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 and oxygen can bond in a number of ways: chlorine monoxide radical, ClO•, chlorine (II) oxide radical; chloroperoxyl radical, ClOO•, chlorine (II) peroxide radical; chlorine dioxide, ClO 2, chlorine (IV) oxide; chlorine trioxide radical, ClO 3 •, chlorine (VI) oxide radical; chlorine tetroxide radical, ClO 4 •, chlorine (VII ...

Many mechanisms exist reflecting the myriad types of cross-couplings, including those that do not require metal catalysts. [7] Often, however, cross-coupling refers to a metal-catalyzed reaction of a nucleophilic partner with an electrophilic partner. Mechanism proposed for Kumada coupling (L = Ligand, Ar = Aryl).
