If the structure of each of the two-unit cells shown in is a rock salt structure, zinc blende structure, fluorite structure, antifluorite structure, or none these.

Question

Kumada Coupling: 1. m-Diisobutylbenzene below could hypothetically be synthesized by Friedel-Crafts reaction. Write out the reaction with a mechanism and give two reasons why you would NOT get the desired product. Draw the reaction (NOT a mechanism) for a Kumada coupling to produce the molecule above from m-dichlorobenzene. Calculate the theoretical yield for the reaction in question 2 using 1.5 g of p-dichlorobenzene and 3.0 mL isobutyl bromide. What signals appeared/disappeared/shifted that indicate that you have your intended product and not starting material? What other impurities are present in your product and how do you know?
