Polycyclic aromatic hydrocarbons (PAHs, also polyaromatic hydrocarbons or polynuclear aromatic hydrocarbons) are hydrocarbons—organic compounds containing only carbon and hydrogen—that are composed of multiple aromatic rings (organic rings in which the electrons are delocalized).The simplest such chemicals are naphthalene, having two aromatic rings, and the . Kinetics of Hydrogen Abstraction Reactions from Polycyclic Aromatic Hydrocarbons by H Atoms Article in The Journal of Physical Chemistry A (22) June with 75 . Free Radical Reactions of Hydrocarbons at Aqueous Interfaces Chemical reactions that occur at hydrocarbon/water and electrolyte interfaces govern a wide array of environmentally and technologically important processes, including electrochemistry, aerosol photo-oxidation, cloud chemistry, corrosion, and heterogeneous catalysis. In organic chemistry, an alkane, or paraffin (a historical name that also has other meanings), is an acyclic saturated other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single. Alkanes have the general chemical formula C n H 2n+ alkanes range in complexity from the simplest case .
Hydroxyl radical is generated by the thermolysis of a tert-butyl azohydroperoxide which dissociates to yield hydroxyl and tert-butyl radicals, nitrogen, and acetone. TMIO is used to trap the tert-butyl radical, but is less likely to trap hydroxyl radical, which is free to react with the target arene to yield a hydroxycyclohexadienyl species.

These structures can contain the elements carbon, hydrogen, oxygen, nitrogen and by: Repetitive hydrogen-abstraction and methyl- and acetylene-addition reaction sequences that contribute to the formation and growth of polycyclic aromatic hydrocarbons (PAHs) during .
Free-radical hydrogen abstraction from polycyclic aliphatic hydrocarbons. Selective reduction of aliphatic ketones and aldehydes to hydrocarbons with sodium cyanoborohydride and p-toluenesulfonyl hydrazide in dimethylformamide-sulfolane. Journal of the American Chemical Society Density functional B3LYP/G(d) and ab initio G3(MP2,CC) calculations have been carried out to determine thermal rate constants of direct H abstraction reactions from four- and five-ring polycyclic aromatic hydrocarbons (PAH) chrysene and benzo[a]pyrene by various radicals abundant in combustion flames, such as H, CH 3, C 3 H 3, and OH, using transition state theory. All fuel oils consist of complex mixtures of aliphatic and aromatic hydrocarbons, the relative amounts depending on the source and grade of the fuel oil. The aliphatic alkanes (paraffins) and cycloalkane constituents (naphthene constituents) are hydrogen saturated and compose as much as 90% w/w of the fuel oil. I need to know if an aliphatic hydrocarbon would react faster than a benzylic in free-radical bromination. I know that the hydrocarbons will react faster in this situation based on their stability. My guess is benzylic because the extra aromatic carbon atom would make the compound more stable, but I'm not very good wtih aromatic carbon rules so I could use some .
