  2. Bent's rule - Wikipedia

    en.wikipedia.org/wiki/Bent's_rule

    [5] [22] For instance, a modification of this analysis is still viable, even if the lone pairs of H 2 O are considered to be inequivalent by virtue of their symmetry (i.e., only s, and in-plane p x and p y oxygen AOs are hybridized to form the two O-H bonding orbitals σ O-H and lone pair n O (σ), while p z becomes an inequivalent pure p ...

  3. Oxygen compounds - Wikipedia

    en.wikipedia.org/wiki/Oxygen_compounds

    Compounds containing oxygen in other oxidation states are very uncommon: − 1 ⁄ 2 (superoxides), − 1 ⁄ 3 , 0 (elemental, hypofluorous acid), + 1 ⁄ 2 , +1 (dioxygen difluoride), and +2 (oxygen difluoride). Oxygen is reactive and will form oxides with all other elements except the noble gases helium, neon, argon and krypton. [1]

    2 cro(o 2) 2 + 7 h 2 o 2 + 6 h + → 2 cr 3+ + 10 h 2 o + 7 o 2 Stable adducts of the type CrO(O 2 ) 2 L include those with L = diethyl ether , 1-butanol , ethyl acetate , or amyl acetate . They form by adding a layer of the organic solvent above the chromate/dichromate solution and shaking during the addition of hydrogen peroxide.

  5. Chemical bonding of water - Wikipedia

    en.wikipedia.org/wiki/Chemical_bonding_of_water

    2 O is sp 3 hybridized in which the 2s atomic orbital and the three 2p orbitals of oxygen are hybridized to form four new hybridized orbitals which then participate in bonding by overlapping with the hydrogen 1s orbitals. As such, the predicted shape and bond angle of sp 3 hybridization is tetrahedral and 109.5°. This is in open agreement with ...

  6. Lone pair - Wikipedia

    en.wikipedia.org/wiki/Lone_pair

    The s character rich O σ(out) lone pair orbital (also notated n O (σ)) is an ~sp 0.7 hybrid (~40% p character, 60% s character), while the p lone pair orbital (also notated n O (π)) consists of 100% p character. Both models are of value and represent the same total electron density, with the orbitals related by a unitary transformation.

  7. Orbital hybridisation - Wikipedia

    en.wikipedia.org/wiki/Orbital_hybridisation

    Chemist Linus Pauling first developed the hybridisation theory in 1931 to explain the structure of simple molecules such as methane (CH 4) using atomic orbitals. [2] Pauling pointed out that a carbon atom forms four bonds by using one s and three p orbitals, so that "it might be inferred" that a carbon atom would form three bonds at right angles (using p orbitals) and a fourth weaker bond ...

    en.wikipedia.org/wiki/Hydroxyl_radical

    Skeletal formulae of 1-hydroxy-2()-pyridinethione and its tautomer. The hydroxyl radical, • HO, is the neutral form of the hydroxide ion (HO –).Hydroxyl radicals are highly reactive and consequently short-lived; however, they form an important part of radical chemistry.

  9. Organic peroxides - Wikipedia

    en.wikipedia.org/wiki/Organic_peroxides

    In organic chemistry, organic peroxides are organic compounds containing the peroxide functional group (R−OO−R′). If the R′ is hydrogen, the compounds are called hydroperoxides, which are discussed in that article. The OO bond of peroxides easily breaks, producing free radicals of the form RO • (the dot represents an unpaired ...
