The phrase "alkyl radical" is correct and usable in written English.
It is typically used in the context of organic chemistry to refer to a specific type of molecular fragment that contains carbon and hydrogen atoms, with one or more hydrogen atoms removed.
Example: "In the reaction, the alkyl radical formed is highly reactive and can lead to further chemical transformations."
Alternatives: "alkyl group" or "alkyl moiety".
The alkyl radical trapping mechanism is discussed.
For the longer chain adducts, metallic silver, carbon dioxide and an alkyl radical, which subsequently combined with another such radical, were proposed [149] in agreement with Akanni [20].
Radical HO attacks the hydrocarbon, RH, to generate alkyl radical, R, which very rapidly reacts with molecular oxygen.
A secondary alkylether radical and a tertiary alkyl radical were identified by ESR in PCL and PDXO-X after irradiation in both air and argon.
They are the backward reaction of second O2 addition, RO2 ⇔ alkene + HO2, QOOH ⇔ cyclic-ether + OH, QOOH ⇔ alkene + HO2, and the beta scission reaction of the alkyl radical.
The detection of longer-lived allyl radicals detected for PE is explained in terms of alkyl radical disproportionation with subsequent reaction of the product alkene.
Asc∙ formation may be induced by nearly all ROS intrinsic to the biological environment, including superoxide radicals, hydroxyl radicals, alkyl peroxyl radicals, lipid peroxyl radicals, peroxynitrite, thiyl radicals, protein radicals, and catalytic metals [ 7].
However, the size of the alkyl or aryl radical has a minor effect on polymer Tg when difunctional quaternizing agents are used.
OH radical and atomic oxygen firstly abstract hydrogen from alkyl chains and then produce alkyl radicals.
Then alkyl radicals react to form alkoxy radicals, further producing reactive carbonyls through oxidation.
It is also important, however, to trap alkyl radicals for prevention of such degradation, because autoxidation includes both peroxy and alkyl radicals as chain carriers.
