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?
CCH H20, H2SO4 H9SO4 CH3 Alkynes do not react directly with aqueous acid as do alkenes, but will do so in the presence of mercury(II) sulfate as a Lewis acid catalyst. The reaction occurs with Markovnikov regiochemistry, so the OH group adds to the more highly substituted carbon and the H adds to the less highly substituted carbon. The initial product of the reaction is a vinyl alcohol, also called an enol. The enol immediately rearranges to a more stable ketone via tautomerization. Draw curved arrows to show the movement of electrons in this step of the mechanism. Arrow-pushing Instructions Hjö: -CH3 -CH3 H3O*
Which represents an efficient synthetic route to go from an alkane to an alkene? O elimination with NaNH2, followed by a water workup O anti-Markovnikov hydrohalogenation, followed by elimination O radical bromination, followed by elimination O hydration, followed by elimination O hydration, followed by ozonolysis of the double bond
A benzene ring alters the reactivity of a neighboring group in the so-called “benzylic” position, similarly to how a double bond alters the reactivity of groups in the “allylic” position. Benzylic cations, anions, and radicals are all more stable than simple alkyl intermediates. a) Use resonance structures to show the delocalization of the positive charge, negative charge, and unpaired electron of the benzyl cation, anion, and radical.
Preparation of alkenes (Elimination reaction)
Generally, addition of halogen acids to alkene follows Markovnikov rule. In which condition the anti-Markovnikov rule is followed? Describe the mechanism with an example.
Which statement about Markovnikov's rule is correct? Radical addition of HBr to an alkene produces a Markovnikov product. Markovnikov's rule dictates that the more stable alkene is the major product. Addition of water to alkenes via hydroboration-oxidation produces a Markovnikov product. O Markovnikov's rule is a consequence of carbocation intermediate stability. Markovnikov's rule dictates that hydrogen is attracted to the side of the alkene with more hydrogens through intramolecular forces.
Zaitsev's rule is useful in selecting which carbon adjacent to a carbocation will form the double bond in the alkene product. True or False
In free-radical substitution reaction of alkanes with halogens under uv light, the photolytic breaking of the halogen is the rate determining step. the formation of alkylradical is the rate determining step. the formation of halogen radical is the rate determining step. the abstraction of hydrogen from alkane by the halogen radical is the rate determining step
Zaitsev's rule: states " The alkene formed in greatest amount is the one that corresponds to O A. removal of the hydrogen from the alpha-carbon having the fewest hydrogen substituents O B. removal of the hydrogen from the any-carbon having the fewest hydrogen substituents OC. removal of the water molecule from the alpha-carbon having the fewest hydrogen substituents D. removal of the hydroxyl (OH) from the any carbon having the fewest hydrogen substituents O E. addition of hydrogen to more substituted carbon atom Reset Selection Previous Next Save 26°C Sunny DELL 立
