188 ChemActivity 20 Radical Halogenation of Aanes Model 8: Selectivity of the Photo-Halogenation Reaction • Radical halogenation with F, is unselective, violent and dangerous limiting the usefulness of this reaction in organic synthesis. • Radical halogenation with le is so slow as to be useless in organic synthesis • Radical halogenation with Br, is right It is very useful in organic synthesis. The rate is manageable and reactions with Br, are very...

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...

True/False Indicate whether the statement is (A) true or (B) false. In the most stable conformation of a cyclohexane, it is preferable to have as many substituents in the axial position as possible. 2. 3. Syl reactions may involve a carbocation rearrangement. Tertiary alkyl halides are more likely to participate in an Sy2 reaction. 4. Cis-1,3-dimethyleyclohexane and trans-1,3-cyclohexane are enantiomers. 5. 6. An Sy2 reaction results in inversion of the relative configuration. The rate of an SNl reaction can be...

What is Wrong?
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...
