  2. Bromine dioxide - Wikipedia

    en.wikipedia.org/wiki/Bromine_dioxide

    Bromine dioxide is the chemical compound composed of bromine and oxygen with the formula BrO 2.It forms unstable yellow [2] to yellow-orange [1] crystals. It was first isolated by R. Schwarz and M. Schmeißer in 1937 and is hypothesized to be important in the atmospheric reaction of bromine with ozone. [3]

  3. Bromine oxide - Wikipedia

    en.wikipedia.org/wiki/Bromine_oxide

    Bromine dioxide (BrO 2). Bromine can form several different oxides: . Dibromine monoxide (Br 2 O); Bromine dioxide (BrO 2); Dibromine trioxide (Br 2 O 3); Dibromine pentoxide (Br 2 O 5); Tribromine octoxide (Br 3 O 8)

    Therefore, there is a resonance structure. Tie up loose ends. Two Lewis structures must be drawn: Each structure has one of the two oxygen atoms double-bonded to the nitrogen atom. The second oxygen atom in each structure will be single-bonded to the nitrogen atom.

  5. Bromine monoxide radical - Wikipedia

    en.wikipedia.org/wiki/Bromine_monoxide_radical

    Bromine monoxide is a binary inorganic compound of bromine and oxygen with the chemical formula BrO. [1] [2] A free radical, this compound is the simplest of many bromine oxides. The compound is capable of influencing atmospheric chemical processes. [3] Naturally, BrO can be found in volcanic plumes.

    en.wikipedia.org/wiki/Linnett_Double-Quartet_Theory

    The LDQ structure of the ground state of O 2 does not involve any electron pairs, in contrast with the Lewis structure of the molecule. Instead, the electrons are arranged as shown below. The LDQ structure of molecular oxygen in the ground state (3 Σ g − state). The oxygen nuclei are coloured red while the electrons are coloured either ...

  7. Natural resonance theory - Wikipedia

    en.wikipedia.org/wiki/Natural_Resonance_Theory

    Given a list of NBOs for an idealized natural Lewis structure, the NRT functional creates a list of Lewis resonance structures and calculates the resonance weights of each contributing resonance structure. [1] Structural and chemical properties, such as bond order, valency, and bond polarity, may be calculated from resonance weights. [2]

  8. Bromine compounds - Wikipedia

    Industrially, it is mainly produced by the reaction of hydrogen gas with bromine gas at 200–400 °C with a platinum catalyst. However, reduction of bromine with red phosphorus is a more practical way to produce hydrogen bromide in the laboratory: [2] 2 P + 6 H 2 O + 3 Br 2 → 6 HBr + 2 H 3 PO 3 H 3 PO 3 + H 2 O + Br 2 → 2 HBr + H 3 PO 4

  9. Formal charge - Wikipedia

    en.wikipedia.org/wiki/Formal_charge

    Formal charges in ozone and the nitrate anion. In chemistry, a formal charge (F.C. or q*), in the covalent view of chemical bonding, is the hypothetical charge assigned to an atom in a molecule, assuming that electrons in all chemical bonds are shared equally between atoms, regardless of relative electronegativity.
