  2. Radical (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Radical_(chemistry)

    In chemistry, a radical, also known as a free radical, is an atom, ... When a hydrocarbon is burned, a large number of different oxygen radicals are involved.

  3. Hydroxy group - Wikipedia

    en.wikipedia.org/wiki/Hydroxy_group

    Both the negatively charged anion HO −, called hydroxide, and the neutral radical HO·, known as the hydroxyl radical, consist of an unbonded hydroxy group. According to IUPAC definitions, the term hydroxyl refers to the hydroxyl radical (·OH) only, while the functional group −OH is called a hydroxy group. [1]

  4. Hydroxyl radical - Wikipedia

    en.wikipedia.org/wiki/Hydroxyl_radical

    The hydroxyl radical, • HO, is the neutral form of the hydroxide ion (HO –). Hydroxyl radicals are highly reactive and consequently short-lived; however, they form an important part of radical chemistry .

  5. Hydrocarbon - Wikipedia

    en.wikipedia.org/wiki/Hydrocarbon

    In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. [1]: ... The reactions proceed via free-radical pathways, ...

  6. Non-Kekulé molecule - Wikipedia

    en.wikipedia.org/wiki/Non-Kekulé_molecule

    A non-Kekulé molecule is a conjugated hydrocarbon that cannot be assigned a classical Kekulé structure [definition needed]. Since non-Kekulé molecules have two or more formal charges or radical centers, their spin-spin interactions can cause electrical conductivity or ferromagnetism ( molecule-based magnets ), and applications to functional ...

  7. Radical disproportionation - Wikipedia

    en.wikipedia.org/wiki/Radical_disproportionation

    Alkyl radical disproportionation has been studied extensively in scientific literature. [6] During alkyl radical disproportionation, an alkane and an alkene are the end products and the bond order of the products increases by one over the reactants. [1] Thus the reaction is exothermic (ΔH = 50–95 kcal/mol (210–400 kJ/mol)) and proceeds ...

  8. Beta scission - Wikipedia

    en.wikipedia.org/wiki/Beta_scission

    Beta scission is an important reaction in the chemistry of thermal cracking of hydrocarbons and the formation of free radicals. Free radicals are formed upon splitting the carbon-carbon bond. Free radicals are extremely reactive and short-lived.

  9. Methyl group - Wikipedia

    en.wikipedia.org/wiki/Methyl_group

    This hydrocarbon group occurs in many organic compounds. It is a very stable group in most molecules. It is a very stable group in most molecules. While the methyl group is usually part of a larger molecule , bonded to the rest of the molecule by a single covalent bond ( −CH 3 ), it can be found on its own in any of three forms: methanide ...
