Reaction mechanism for methane and bromine
WebMay 1, 2003 · At temperatures near 800 C with excess methane, conversions of bromine to HBr exceeded 90% and reaction products included solid carbon (soot) in stoichiometric amounts. At lower temperatures, HBr conversion was significantly reduced, the products included much less soot, and the formation of bromocarbon compounds was indicated … WebApr 8, 2024 · In other words, the reaction position of premixed methane laid on both sides of the heat exchange tube rather than between the two tubes. The flame front propagated outward from the reaction position with a higher temperature gradient. In contrast, the central region in the burner between two heat exchange tubes was forced to form an …

WebThe two-step mechanism shown in the LibreText pages gives you an idea of how the reaction between an alkene and a halogen occurs. Note the formation of the bridged bromonium ion intermediate and the anti stereochemistry of the final product because the two bromine atoms come from opposite faces of the double bond. http://home.miracosta.edu/dlr/102exp2.htm
Web4. Know the meaning of: substitution reaction, halogenation, chlorination, bromination, free-radical chain reaction, chain initiation, propagation, termination, combustion. 5. Given the IUPAC name of an alkane or cycloalkane, or a halogen-substituted alkane or cycloalkane, draw its structural formula. 6. WebRADICAL CHAIN MECHANISM FOR REACTION OF METHANE WITH Br2. Step 1 (Initiation) Heat or uv light cause the weak halogen bond to undergo homolytic cleavage to generate two bromine radicals and starting the chain process. Step 2 (Propagation) (a) A bromine radical abstracts a hydrogen to form HBr and a methyl radical, then.
