  2. Orbital hybridisation - Wikipedia

    en.wikipedia.org/wiki/Orbital_hybridisation

    In chemistry, orbital hybridisation (or hybridization) is the concept of mixing atomic orbitals to form new hybrid orbitals (with different energies, shapes, etc., than the component atomic orbitals) suitable for the pairing of electrons to form chemical bonds in valence bond theory.

  3. Bent's rule - Wikipedia

    en.wikipedia.org/wiki/Bent's_rule

    This is a weighted sum of the wavefunctions. Now choose a second hybrid orbital s + √ λ j p j, where p j is directed in some way and λ j is the amount of p character in this second orbital. The value of λ j and direction of p j must be determined so that the resulting orbital can be normalized and so that it is orthogonal to the first ...

  4. Localized molecular orbitals - Wikipedia

    en.wikipedia.org/wiki/Localized_molecular_orbitals

    For instance, the lone pairs of water are usually treated as two equivalent sp x hybrid orbitals, while the corresponding "nonbonding" orbitals of carbenes are generally treated as a filled σ(out) orbital and an unfilled pure p orbital, even though the lone pairs of water could be described analogously by filled σ(out) and p orbitals (for ...

  5. 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

  6. Valence bond theory - Wikipedia

    en.wikipedia.org/wiki/Valence_bond_theory

    Hybridization is a model that describes how atomic orbitals combine to form new orbitals that better match the geometry of molecules. Atomic orbitals that are similar in energy combine to make hybrid orbitals. For example, the carbon in methane (CH 4) undergoes sp 3 hybridization to form four equivalent orbitals, resulting in a tetrahedral shape.

  7. Isovalent hybridization - Wikipedia

    en.wikipedia.org/wiki/Isovalent_hybridization

    In chemistry, isovalent or second order hybridization is an extension of orbital hybridization, the mixing of atomic orbitals into hybrid orbitals which can form chemical bonds, to include fractional numbers of atomic orbitals of each type (s, p, d). It allows for a quantitative depiction of bond formation when the molecular geometry deviates ...

  8. Orbital overlap - Wikipedia

    en.wikipedia.org/wiki/Orbital_overlap

    In chemical bonds, an orbital overlap is the concentration of orbitals on adjacent atoms in the same regions of space. Orbital overlap can lead to bond formation. Linus Pauling explained the importance of orbital overlap in the molecular bond angles observed through experimentation; it is the basis for orbital hybridization.

  9. Linear combination of atomic orbitals - Wikipedia

    en.wikipedia.org/wiki/Linear_combination_of...

    where is a molecular orbital represented as the sum of n atomic orbitals , each multiplied by a corresponding coefficient , and r (numbered 1 to n) represents which atomic orbital is combined in the term. The coefficients are the weights of the contributions of the n atomic orbitals to the molecular orbital.
