  2. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.

  3. Structural formula - Wikipedia

    en.wikipedia.org/wiki/Structural_formula

    This is helpful when converting from condensed formula to another form of structural formula such as skeletal formula or Lewis structures. There are different ways to show the various functional groups in the condensed formulas such as aldehyde as CHO, carboxylic acids as CO 2 H or COOH, esters as CO 2 R or COOR. However, the use of condensed ...

  4. Pentacarbonylhydridomanganese - Wikipedia

    en.wikipedia.org/wiki/Pentacarbonylhydridomanganese

    The structure of HMn(CO) 5 has been studied by many methods including X-ray diffraction, neutron diffraction, and electron diffraction. [5] HMn(CO) 5 can be related to the structure of a hexacarbonyl complex such as Mn(CO) + 6, and therefore has similar properties. [6]

  5. Carbon monoxide - Wikipedia

    en.wikipedia.org/wiki/Carbon_monoxide

    Carbon monoxide (chemical formula CO) is a poisonous, flammable gas that is colorless, odorless, tasteless, and slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond. It is the simplest carbon oxide. In coordination complexes, the carbon monoxide ligand is called carbonyl. It is ...

  6. Lewis acids and bases - Wikipedia

    en.wikipedia.org/wiki/Lewis_acids_and_bases

    In a Lewis adduct, the Lewis acid and base share an electron pair furnished by the Lewis base, forming a dative bond. [1] In the context of a specific chemical reaction between NH 3 and Me 3 B, a lone pair from NH 3 will form a dative bond with the empty orbital of Me 3 B to form an adduct NH 3 •BMe 3.

  7. Oxidation state - Wikipedia

    en.wikipedia.org/wiki/Oxidation_state

    Carbon monoxide exemplifies a Lewis structure with formal charges: To obtain the oxidation states, the formal charges are summed with the bond-order value taken positively at the carbon and negatively at the oxygen. Applied to molecular ions, this algorithm considers the actual location of the formal (ionic) charge, as drawn in the Lewis structure.

  8. Formal charge - Wikipedia

    en.wikipedia.org/wiki/Formal_charge

    Example: CO 2 is a neutral molecule with 16 total valence electrons.There are different ways to draw the Lewis structure Carbon single bonded to both oxygen atoms (carbon = +2, oxygens = −1 each, total formal charge = 0)

  9. Carbonyl group - Wikipedia

    en.wikipedia.org/wiki/Carbonyl_group

    A ketone compound containing a carbonyl group (C=O) In organic chemistry, a carbonyl group is a functional group with the formula C=O, composed of a carbon atom double-bonded to an oxygen atom, and it is divalent at the C atom.
