1. Give the detailed arrow-pushing mechanism for the free radical polymerization of methyl methacrylate. Show the initiation step and the addition of at least 2 monomers. You do not need to show a termination step, but do show the [ Jn notation of the final polymer. NEATNESS COUNTS heat poly(methyl methacrylate methyl methacrylate The initiator in this experiment, benzoyl peroxide, contains a weak 0-0 bond that undergoes homolytic cleavage at elevated temperatures. This leads to...

2. The addition of HBr to 2-methylpropene can, in principle, give either 1-bromo-2- methylpropane or 2-bromo-2-methylpropane. In reality, only the latter is formed. Show mechanisms for the formation of each of these alkyl bromides, using curved arrows to indicate the flow of electron pairs. Also, construct reaction energy diagrams that describe the energy of the system as a function of the progress in formation of both alkyl bromides. Use these reaction coordinate diagrams to explain why 2-bromo-2-methylpropane is the only...

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
