  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. Carbon–oxygen bond - Wikipedia

    en.wikipedia.org/wiki/Carbon–oxygen_bond

    Carbon–oxygen bond. A carbon–oxygen bond is a polar covalent bond between atoms of carbon and oxygen. [1][2][3]: 16–22 Carbon–oxygen bonds are found in many inorganic compounds such as carbon oxides and oxohalides, carbonates and metal carbonyls, [4] and in organic compounds such as alcohols, ethers, and carbonyl compounds. [5]: 32–36 ...

  4. Molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Molecular_geometry

    Molecular geometry. Geometry of the water molecule with values for O-H bond length and for H-O-H bond angle between two bonds. Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule. It includes the general shape of the molecule as well as bond lengths, bond angles, torsional angles and any other ...

  5. Chemical bond - Wikipedia

    en.wikipedia.org/wiki/Chemical_bond

    The atoms in molecules, crystals, metals and other forms of matter are held together by chemical bonds, which determine the structure and properties of matter. All bonds can be described by quantum theory, but, in practice, simplified rules and other theories allow chemists to predict the strength, directionality, and polarity of bonds. [4]

  6. Carbon–nitrogen bond - Wikipedia

    en.wikipedia.org/wiki/Carbon–nitrogen_bond

    Carbon–nitrogen bond. A carbon–nitrogen bond is a covalent bond between carbon and nitrogen and is one of the most abundant bonds in organic chemistry and biochemistry. [ 1 ] Nitrogen has five valence electrons and in simple amines it is trivalent, with the two remaining electrons forming a lone pair. Through that pair, nitrogen can form an ...

  7. 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 ...

  8. 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 ...

  9. Chemical structure - Wikipedia

    en.wikipedia.org/wiki/Chemical_structure

    Chemical structure. A chemical structure of a molecule is a spatial arrangement of its atoms and their chemical bonds. Its determination includes a chemist 's specifying the molecular geometry and, when feasible and necessary, the electronic structure of the target molecule or other solid. Molecular geometry refers to the spatial arrangement of ...
