  2. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    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. Polar molecules must contain one or more polar bonds due to a difference in electronegativity between the bonded atoms.

  3. 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 ...

  4. 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 ...

  5. Tetrahedral molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Tetrahedral_molecular_geometry

    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 ...

  6. Nitromethane - Wikipedia

    en.wikipedia.org/wiki/Nitromethane

    Nitromethane, sometimes shortened to simply "nitro", is an organic compound with the chemical formula CH. 3NO. 2. It is the simplest organic nitro compound. It is a polar liquid commonly used as a solvent in a variety of industrial applications such as in extractions, as a reaction medium, and as a cleaning solvent.

  7. Carbon tetrachloride - Wikipedia

    en.wikipedia.org/wiki/Carbon_tetrachloride

    Because of this symmetric geometry, CCl 4 is non-polar. Methane gas has the same structure, making carbon tetrachloride a halomethane . As a solvent , it is well suited to dissolving other non-polar compounds such as fats and oils.

  8. Carbon tetrafluoride - Wikipedia

    en.wikipedia.org/wiki/Carbon_tetrafluoride

    Infobox references. Tetrafluoromethane, also known as carbon tetrafluoride or R-14, is the simplest perfluorocarbon (C F 4). As its IUPAC name indicates, tetrafluoromethane is the perfluorinated counterpart to the hydrocarbon methane. It can also be classified as a haloalkane or halomethane.

  9. Van der Waals force - Wikipedia

    en.wikipedia.org/wiki/Van_der_Waals_force

    In molecular physics and chemistry, the van der Waals force (sometimes van de Waals' force) is a distance-dependent interaction between atoms or molecules. Unlike ionic or covalent bonds, these attractions do not result from a chemical electronic bond; [2] they are comparatively weak and therefore more susceptible to disturbance.
