  2. Carbonic acid - Wikipedia

    en.wikipedia.org/wiki/Carbonic_acid

    Carbonic acid is a chemical compound with the chemical formula H 2 C O 3. The molecule rapidly converts to water and carbon dioxide in the presence of water. However, in the absence of water, it is quite stable at room temperature .

  3. Carbon compounds - Wikipedia

    en.wikipedia.org/wiki/Carbon_compounds

    Carbon compounds are defined as chemical substances containing carbon. [1] [2] More compounds of carbon exist than any other chemical element except for hydrogen. Organic carbon compounds are far more numerous than inorganic carbon compounds. In general bonds of carbon with other elements are covalent bonds.

    The latter is consistent with the pK a ’s of carbonic acid: pK 1 = 6.77 and pK 2 = 9.93. To a single metal ion, carbonate is observed to bind in both unidentate (κ 1-) and bidentate (κ 2-) fashions. [5] In the covalent bond classification method, κ 1-carbonate is anX ligand and κ 2-carbonate is an X 2 ligand.

  5. Carbonate ester - Wikipedia

    en.wikipedia.org/wiki/Carbonate_ester

    In organic chemistry, a carbonate ester (organic carbonate or organocarbonate) is an ester of carbonic acid. This functional group consists of a carbonyl group flanked by two alkoxy groups. The general structure of these carbonates is R−O−C(=O)−O−R' and they are related to esters ( R−O−C(=O)−R' ), ethers ( R−O−R' ) and also to ...

  6. Carbonyl group - Wikipedia

    en.wikipedia.org/wiki/Carbonyl_group

    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. It is common to several classes of organic compounds (such as aldehydes , ketones and carboxylic acid ), as part of many larger functional groups.

    That is, they are the conjugate bases of polycarbonic acids, the conceptual anhydrides of carbonic acid, or polymers of carbon dioxide. They have the structure – O[(C=O)–O] n – and the molecular formula [C n O 2 n +1 ] 2– .

  8. Carbonated water - Wikipedia

    en.wikipedia.org/wiki/Carbonated_water

    Bonds in carbonic acid are more easily broken at high temperatures resulting in the generation of water and gaseous carbon dioxide. Thus sparkling water at lower temperatures (far right) holds more carbonation than at high (far left). [18] Carbon dioxide gas dissolved in water creates a small amount of carbonic acid (H 2 CO 3): H 2 O (l) + CO 2 ...

  9. Chemical bond - Wikipedia

    en.wikipedia.org/wiki/Chemical_bond

    A chemical bond is the association of atoms or ions to form molecules, crystals, and other structures. The bond may result from the electrostatic force between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds, or some combination of these effects.
