c. The reaction of triphenylphosphine with an alkyl halide is a
bimolecular nucleophilic substitution (SN2) reaction in which
triphenylphosphine is the nucleophile and the alkyl halide is
theelectrophile. Is triphenylphosphine acting like a Lewis acid,
Lewis base, Bronsted-Lowry acid, orBronsted-Lowry base? How would
you characterize the behavior of the alkyl halide?
d. In the lab, you will make your ylide by reacting
benzyltriphenylphosphonium bromide with sodium hydroxide. How would
you characterize this reaction?
e. Is the ylide that you form...

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...
