Select the keyword or phrase that will best complete each sentence. Key terms: A radical is a reactive intermediate with a single unpaired electron, formed by homoloysis of a covalent bond. paired unpaired Allylic radicals are stabilized by resonance, making them more stable than tertiary radicals increases inductive effects A compound that contains an especially weak bond that serves as a source of radicals is called a radical initiator ess homoloysis decreases more J Treatment of cyclohexene...

4) Radicals in some instances can lead to undesired reactions. Foods are known to contain radical inhibitors, known as preservatives or antioxidants. These species act by preventing radical chain reactions that can lead to degradation of packaged foods. One synthetic preservative used commonly in both the food industry and the chemical industry is BHT (butylated hydroxytoluene), shown below. Using your knowledge of radical chain mechanisms, draw the propagation steps for the reaction of BHT with an alkyl radical (R) (9...

1. The methoxy radical, CH30, is formed by the reaction: CH3O2 + NO - CH3O + NO2 and reacts via: CH30 + 02 - HCHO + HO2 (a) Write down an expression for the steady state concentration of CH30. (b) What is the fate of HCHO in the atmosphere? How do the different possible reactions influence the total number of radicals in the atmosphere?

III IV 5. The product of free-radical halogenation reactions is an alkyl halide. The major amount of this halide forms during the second step of propagation. However, you should be aware that one possible termination step also forms alkyl halides. Why does the majority of the alkyl halide product come from the propagation step and not the termination step? A. At any given time during the reaction, the concentration of both the alkyl radical and the halide...
