- (b) Addition of HBr to the alkene in the presence of peroxide form radical intermediates. Based on the following reaction, use the curved arrows to HBr B (preferred product) ROOR (i) show the initiation step of this reaction. (ii) draw the possible structures of the two radicals formed in the propagation step. (ii) explain the formation of the preferred product B.arrow_forwardA student adds NBS to a solution of 1-methylcyclohexene and irradiates the mixture with a sunlamp until all the NBS has reacted. After a careful distillation, the product mixture contains two major products of formula C7H11Br. (a) Draw the resonance forms of the three possible allylic free radical intermediates.arrow_forwardWrite a step by step mechanism. Includes resonance structures that exist in the transition states.arrow_forward
- This molecule reacts with HBr to form an alkyl halide. Is this reaction Sn1 or Sn2 and explain your reasoning?arrow_forwardThe above reaction involves heterolytic bond breakage of HBr a) Encircle the nucleophile (s) and electrophile (s) and explain why. b) Give the mechanism of the reaction by: ) Drawing the appropriate arrows to track the flow of electrons in Showing the species formed after bond breakage and bond formation with appropriate charges. c) Predict the final products.arrow_forwardAs we will learn, many antioxidants–compounds that prevent unwanted radical oxidation reactions from occurring–are phenols, compounds that contain an OH group bonded directly to a benzene ring.a.) Explain why homolysis of the O–H bond in phenol requiresconsiderably less energy than homolysis of the O–H bond in ethanol(362 kJ/mol vs. 438 kJ/mol).b.) Why is the C–O bond in phenol shorter than the C–O bond in ethanol?arrow_forward
- a) Write the name of three steps of free-radical halogenation of methane?b) Give the mechanism of formation of dichloromethane from chloromethane?c) Explain why free-radical halogenation usually gives mixture of products.arrow_forwardWrite the complete reaction mechanism of this reaction including resonance structures of all the productsarrow_forwardWhen piperidine undergoes the series of reactions shown here, 1,4-pentadiene is obtained as the product. When the four different methyl- substituted piperidines undergo the same series of reactions, each forms a different diene: 1,5-hexadiene; 1,4-pentadiene; 2-methyl-1,4-pentadiene; and 3-methyl-1,4-pentadiene. Which methyl-substituted piperidine forms which diene?arrow_forward
- )a) The radical chlorination of pentane is a poor way to prepare 1-chloropentane but radical chlorination of neopentane, (CH).C, is a good way to prepare neopentyl chloride, (CH) CCH;CI. Explain. b) Show the mechanism for the radical chlorination of neopentane. Illustrate homolytic bond cleavage and bond formation.arrow_forwardb) Explain in detail what characteristics of the alkyl halide influence whether a mechanism will be SN1 or SN2. c) Explain in detail what characteristics of a nucleophile influence whether a reaction will be SN1 or SN2.arrow_forward3. Nucleophilic aromatic substitution (NAS) reactions have the opposite trend in terms of reaction rate when compared with SN2 reaction rates. This is to say that aromatic fluorides undergo substitution the fastest under NAS conditions but the slowest under SN2 conditions. Using your knowledge of the mechanisms of these reactions, explain why this is the case. (Hint: It is important to consider the rate-determining step of each mechanism). NuO Nu Rate of reaction follows the following trend: F> CI > Br>1 NuO Nu Rate of reaction follows the following trend: I> Br > CI >Farrow_forward
