  2. Covalent bond - Wikipedia

    en.wikipedia.org/wiki/Covalent_bond

    A double bond between two given atoms consists of one σ and one π bond, and a triple bond is one σ and two π bonds. [8] Covalent bonds are also affected by the electronegativity of the connected atoms which determines the chemical polarity of the bond. Two atoms with equal electronegativity will make nonpolar covalent bonds such as H–H.

  3. 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 ...

  4. Acid strength - Wikipedia

    en.wikipedia.org/wiki/Acid_strength

    Examples of strong acids are hydrochloric acid (), perchloric acid (), nitric acid and sulfuric acid (). A weak acid is only partially dissociated, or is partly ionized in water with both the undissociated acid and its dissociation products being present, in solution, in equilibrium with each other.

  5. Intramolecular force - Wikipedia

    en.wikipedia.org/wiki/Intramolecular_force

    In a true covalent bond, the electrons are shared evenly between the two atoms of the bond; there is little or no charge separation. Covalent bonds are generally formed between two nonmetals. There are several types of covalent bonds: in polar covalent bonds , electrons are more likely to be found around one of the two atoms, whereas in ...

  6. Molecule - Wikipedia

    en.wikipedia.org/wiki/Molecule

    A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are termed shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is termed covalent bonding. [22]

  7. Classes of metals - Wikipedia

    en.wikipedia.org/wiki/Classes_of_metals

    They target molecules such as phospholipids, nucleic acids, and ATP. Class B metals are metals that form soft acids. [2] Soft acids are acids with relatively covalent bonds. These metals, such as lead, gold, palladium, platinum, mercury, and rhodium, would rather bond with iodine than fluorine. They form stable products with soft bases, which ...

  8. Lewis acids and bases - Wikipedia

    en.wikipedia.org/wiki/Lewis_acids_and_bases

    Although there have been attempts to use computational and experimental energetic criteria to distinguish dative bonding from non-dative covalent bonds, [4] for the most part, the distinction merely makes note of the source of the electron pair, and dative bonds, once formed, behave simply as other covalent bonds do, though they typically have ...

  9. Carbon–oxygen bond - Wikipedia

    en.wikipedia.org/wiki/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.
