Question

These compounds migrate and insert into a carbon-zirconium bond in the propagation step of a Kaminsky catalyst. These compounds are the oxidation products when a free radical polymer disproportionates. Catalytic cracking is used to produce these short-chain molecules at an oil refinery. These compounds coordinate aluminum to form vinyl cations that eliminate a beta-hydride in the mechanism of a (*) Ziegler–Natta catalyst. (10[1])The kinked chain of an unsaturated (10[1])fatty (10[1])acid is one of these compounds. (10[4])Industrial plastics (10[1])like PVC or PE are polymers of these compounds, which have formulas of the form (10[1])“C n H two n.” (10[1])For 10 points, (10[1])name these compounds that react together to form poly·olefins and have a carbon-carbon double (10[1])bond. (10[3])■END■ (10[12])

ANSWER: alkenes (“al-KEENS”) [or polyalkenes; acceptolefins or polyolefins until it is read; prompt on hydrocarbons; prompt on monomers until it is read; prompt on unsaturated fatty acid or fatty acid until it is read; listen carefully and reject “alkanes” (“al-KANES”) or “alkynes” (“al-KINES”); reject “plastics”]
