  2. Chemical bonding of water - Wikipedia

    en.wikipedia.org/wiki/Chemical_bonding_of_water

    2 O is sp 2 hybridized. This would be true under the idealized assumption that s and p character are evenly distributed between the two O-H bonds and O lone pair (n O (σ)). However, this prediction (120° bond angles) is inconsistent with the bond angle of H 2 O being 104.5°. The actual hybridization of H

  3. Bent's rule - Wikipedia

    en.wikipedia.org/wiki/Bent's_rule

    In the case of water, with its 104.5° HOH angle, the OH bonding orbitals are constructed from O(~sp 4.0) orbitals (~20% s, ~80% p), while the lone pairs consist of O(~sp 2.3) orbitals (~30% s, ~70% p). As discussed in the justification above, the lone pairs behave as very electropositive substituents and have excess s character.

  4. Isovalent hybridization - Wikipedia

    en.wikipedia.org/wiki/Isovalent_hybridization

    Only bonding with 4 equivalent substituents results in exactly sp 3 hybridization. For molecules with different substituents, we can use isovalent hybridization to rationalize the differences in bond angles between different atoms. In the molecule methyl fluoride for example, the HCF bond angle (108.73°) is less than the HCH bond angle (110.2 ...

  5. Superoxide - Wikipedia

    en.wikipedia.org/wiki/Superoxide

    In chemistry, a superoxide is a compound that contains the superoxide ion, which has the chemical formula O2. [1] The systematic name of the anion is dioxide(1−).The reactive oxygen ion superoxide is particularly important as the product of the one-electron reduction of dioxygen O 2, which occurs widely in nature. [2]

  6. Orbital hybridisation - Wikipedia

    en.wikipedia.org/wiki/Orbital_hybridisation

    For this molecule, carbon sp 2 hybridises, because one π (pi) bond is required for the double bond between the carbons and only three σ bonds are formed per carbon atom. In sp 2 hybridisation the 2s orbital is mixed with only two of the three available 2p orbitals, usually denoted 2p x and 2p y. The third 2p orbital (2p z) remains unhybridised.

  7. Hybridisation - Wikipedia

    en.wikipedia.org/wiki/Hybridisation

    Hybridization (or hybridisation) may refer to: Hybridization (biology) , the process of combining different varieties of organisms to create a hybrid Orbital hybridization , in chemistry, the mixing of atomic orbitals into new hybrid orbitals

  8. Hydroxyl radical - Wikipedia

    en.wikipedia.org/wiki/Hydroxyl_radical

    Hydroxyl radicals are also produced during UV-light dissociation of H 2 O 2 (suggested in 1879) and likely in Fenton chemistry, where trace amounts of reduced transition metals catalyze peroxide-mediated oxidations of organic compounds. In organic synthesis hydroxyl radicals are most commonly generated by photolysis of 1-Hydroxy-2(1H ...

  9. Seesaw molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Seesaw_molecular_geometry

    Disphenoidal or seesaw (also known as sawhorse [1]) is a type of molecular geometry where there are four bonds to a central atom with overall C 2v molecular symmetry.The name "seesaw" comes from the observation that it looks like a playground seesaw.
