  2. Methane - Wikipedia

    en.wikipedia.org/wiki/Methane

    Methane is a tetrahedral molecule with four equivalent C–H bonds. Its electronic structure is described by four bonding molecular orbitals (MOs) resulting from the overlap of the valence orbitals on C and H. The lowest-energy MO is the result of the overlap of the 2s orbital on carbon with the in-phase combination of the 1s orbitals on the ...

  3. Carbon–hydrogen bond - Wikipedia

    en.wikipedia.org/wiki/Carbon–hydrogen_bond

    Carbon–hydrogen bond. In chemistry, the carbon–hydrogen bond (C−H bond) is a chemical bond between carbon and hydrogen atoms that can be found in many organic compounds. [1] This bond is a covalent, single bond, meaning that carbon shares its outer valence electrons with up to four hydrogens. This completes both of their outer shells ...

  4. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    Two charges are present with a negative charge in the middle (red shade), and a positive charge at the ends (blue shade). In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end.

  5. Chemical bond - Wikipedia

    en.wikipedia.org/wiki/Chemical_bond

    Molecules that are formed primarily from non-polar covalent bonds are often immiscible in water or other polar solvents, but much more soluble in non-polar solvents such as hexane. A polar covalent bond is a covalent bond with a significant ionic character. This means that the two shared electrons are closer to one of the atoms than the other ...

  6. Covalent bond - Wikipedia

    en.wikipedia.org/wiki/Covalent_bond

    A covalent bond is a chemical bond that involves the sharing of electrons to form electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs. The stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding. [1] For many molecules, the sharing of ...

  7. Tetrahedral molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Tetrahedral_molecular_geometry

    In a tetrahedral molecular geometry, a central atom is located at the center with four substituents that are located at the corners of a tetrahedron. The bond angles are cos −1 (− 1⁄3) = 109.4712206...° ≈ 109.5° when all four substituents are the same, as in methane (CH4) [1][2] as well as its heavier analogues.

  8. Alkane - Wikipedia

    en.wikipedia.org/wiki/Alkane

    Alkane. In organic chemistry, an alkane, or paraffin (a historical trivial name that also has other meanings), is an acyclic saturated hydrocarbon. In other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single. [1] Alkanes have the general chemical formula CnH2n+2.

  9. Hydrocarbon - Wikipedia

    en.wikipedia.org/wiki/Hydrocarbon

    Hydrocarbon. Ball-and-stick model of the methane molecule, CH 4. Methane is part of a homologous series known as the alkanes, which contain single bonds only. In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. [1]: 620 Hydrocarbons are examples of group 14 hydrides.
