Q:When styrene (vinylbenzene) is commercially polymerized, about 1-3% of 1,4-divinylbenzene is often added to the styrene. The incorporation of someQ:The cationic polymerization of isobutylene (2-methylpropene) is shown in Section 8-16A. Isobutylene is often polymerized under free-radicalQ:Show how you might use olefin metathesis to assemble the following alkenes from smaller units:(a)(b)Q:Cyclohexene is dissolved in a solution of lithium chloride in chloroform. To this solution is added one equivalent of bromine. The material isolatedQ:Draw a reaction-energy diagram for the propagation steps of the free-radical addition of HBr to isobutylene. Draw curves representing the reactionsQ:Give the products expected when the following compounds are ozonized and reduced.(a)(b) (c) (d)Q:Show how you would make the following compounds from a suitable cyclic alkene.(a)(b) (c) (d) (e) (f)Q:Predict the products of the following hydration reactions. (a) 1-methylcyclopentene + dilute acid (b) 2-phenylpropene + dilute acid (c)Q:Unknown X, C5H9Br does not react with bromine or with dilute KMnO4 Upon treatment with potassium tert-butoxide, X gives only one product, YC5H8,Q:One of the constituents of turpentine is α -pinene, formula C10H16 The following scheme (called a "road map") gives some reactions ofQ:The sex attractant of the housefly has the formula C23H46-When treated with warm potassium permanganate, this pheromone gives two products:Q:In contact with a platinum catalyst, an unknown alkene reacts with 3 equivalents of hydrogen gas to give 1-isopropyl-4- methylcyclohexane.
