- In general, what type of compound is expected to be the final product when two halogen atoms add across the double bond of an alkene?Consider the structure of cyclohexene, if it undergoes epoxidation followed by exposure to water, which of the following final product is formed? a. Cyclohexan-1,2,-diol b. Cyclohexane c. Cyclohexanone d. Hexan-1,-6-dioic acidWrite the structural formula and name of the organic product for the reaction between an alkyne and an alkyl halide.The alkyne group is shown, and should be entered, as CCCC , without the triple bond. 1.

- As we will learn in Chapter 28, styrene derivatives such as A can be polymerized by way of cationic rather than radical intermediates. Cationic polymerization is an example of electrophilic addition to an alkene involving carbocations.a.Draw a short segment of the polymer formed by the polymerization of A. b.Why does A react faster than styrene (C6H5CH=CH2) in a cationic polymerization?What is the role of the catalyst in electrophilic aromatic substitution reactions of benzene? O A. The catalyst speeds up the reaction by deprotonating the arenium ion that forms in the reaction. O B. The catalyst attaches to the benzene ring, making it more susceptible to electrophilic substitution OC. The catalyst prevents addition reaction from occurring. O D. The catalyst reacts with the non-benzene reactant to form the electrophile in the reaction.explain the process by which alkenes begin the polymerization process, and how the process continues explain why the bonds of polymers made from alkenes are so stable.
- In general, which of the following statements correctly describes the reactivity of alkenes? Select one: A. An alkene is an electron-rich molecule and therefore can react as a nucleophile. B. Alkenes are generally unreactive compared alkanes. C. Alkenes react as electrophiles, whereas alkanes react as nucleophiles. D. Unlike alkynes, alkenes fail to undergo electrophilic addition reactions. Which of the following statements on bond-breaking (cleaving) or bond-forming is correct? Select one: A. In homolytic bond breaking, a bond is broken respectively by the movement of a pair of electrons in the same direction to one of the products. B. In heterolytic bond-forming, electrons flow from a nucleophile to an electrophile. C. Electron flow in homolytic bond breaking is shown by a double-headed arrow from the bond to a nucleophile. D. A double-headed arrow indicates the movement of an electron pair during homolytic bond breaking.Identify the Type of Product 1-propene + H2O—> 1-propanol a. zaitsev b. markovnikov c. anti-markovnikov d. hoffman1.

Otherwise, change the underlined word/phrase to make it correct. Do not use abbreviations. 1. Hydration is the addition of water to an alkene to form an alkynes. 2. Alkynes undergo addition reactions because they contain relatively strong p bonds. 3. Good nucleophiles that are strong bases favor substitution over elimination.6.
