  2. Methyl group - Wikipedia

    en.wikipedia.org/wiki/Methyl_group

    In organic chemistry, a methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms, having chemical formula CH 3 (whereas normal methane has the formula CH 4). In formulas, the group is often abbreviated as Me. This hydrocarbon group occurs in many organic compounds. It is a very stable group in ...

  3. Triatomic hydrogen - Wikipedia

    en.wikipedia.org/wiki/Triatomic_hydrogen

    Triatomic hydrogen or H 3 is an unstable triatomic molecule containing only hydrogen.Since this molecule contains only three atoms of hydrogen it is the simplest triatomic molecule [1] and it is relatively simple to numerically solve the quantum mechanics description of the particles.

  4. Trihydrogen cation - Wikipedia

    en.wikipedia.org/wiki/Trihydrogen_cation

    The role that H + 3 plays in the gas-phase chemistry of the ISM is unparalleled by any other polyatomic ion. The trihydrogen cation is the simplest triatomic molecule, because its two electrons are the only valence electrons in the system. It is also the simplest example of a three-center two-electron bond system.

  5. Oxygen reduction reaction - Wikipedia

    en.wikipedia.org/wiki/Oxygen_reduction_reaction

    In chemistry, the oxygen reduction reaction refers to the reduction half reaction whereby O 2 is reduced to water or hydrogen peroxide. In fuel cells, the reduction to water is preferred because the current is higher. The oxygen reduction reaction is well demonstrated and highly efficient in nature. [1] [2]

  6. Radical disproportionation - Wikipedia

    en.wikipedia.org/wiki/Radical_disproportionation

    Reactions in radical chemistry can generate both radical and non-radical products. Radical disproportionation reactions can occur with many radicals in solution and in the gas phase . Due to the reactive nature of radical molecules, disproportionation proceeds rapidly and requires little to no activation energy . [ 1 ]

  7. Organic redox reaction - Wikipedia

    en.wikipedia.org/wiki/Organic_redox_reaction

    True organic redox chemistry can be found in electrochemical organic synthesis or electrosynthesis. Examples of organic reactions that can take place in an electrochemical cell are the Kolbe electrolysis. [3] In disproportionation reactions the reactant is both oxidised and reduced in the same chemical reaction forming two separate compounds.

  8. Oxygen compounds - Wikipedia

    en.wikipedia.org/wiki/Oxygen_compounds

    So-called noble metals, such as gold and platinum, resist direct chemical combination with oxygen, and substances like gold(III) oxide (Au 2 O 3) must be formed by an indirect route. The alkali metals and alkali earth metals all react spontaneously with oxygen when exposed to dry air to form oxides, and form hydroxides in the presence of oxygen ...

  9. Protonation - Wikipedia

    en.wikipedia.org/wiki/Protonation

    In chemistry, protonation (or hydronation) is the adding of a proton (or hydron, or hydrogen cation), usually denoted by H +, to an atom, molecule, or ion, forming a conjugate acid. [1] (The complementary process, when a proton is removed from a Brønsted–Lowry acid, is deprotonation.) Some examples include The protonation of water by ...
