8Write the major product formed in the reaction of 2-methyl-2 butene with each of the following and indicate the reaction that occurred in its production (3 pts; 1 pt/ product, 0.5 pt/reaction): A. Bromine in carbon tetrachloride B. Peroxyacetic acid
Stereochemistry of bromine addition 1) To investigate the mechanism for the addition of bromine to an alkene, we will use the melting point of our brominated products. The three possible outcomes for this lab are to obtain 1)only the syn enantiomers, 2)only the anti enantiomers, or 3)a mixture of diastereomers. Match these possible outcomes to the three possible mechanisms described in the lab manual, bromonium ion, concerted Br2 activation, and carbonation 2) In this experiment we don't crystallize the final...
For a Friedel-Crafts alkylation reaction between 1,4-dimethoxybenzene with 3-methyl-2-butanol and sulfuric acid what product was formed in this reaction? Use a discussion of the reaction mechanism, IR, and NMR data to justify your conclusion. A figure should be included to aid in the discussion of the reaction mechanism.
