- Name (including E/Z stereochemistry) the five alkenes that can produce 3-bromo-3-methylhexane on reaction with HBr. Draw the skeletal structure of each molecule.arrow_forwardDraw a structure for the product of nucleophilic substitution obtained on solvolysis of tert-butyl bromide in methanol, and arrange the correct mechanism for its formation. Be sure to answer all parts.arrow_forwardDraw an energy diagram for an E2 reaction: (CH3)3CBr + −OH →(CH3)2C=CH2 + H2O + Br−arrow_forward
- In the reaction (E) 2-methyl -2,4-hexadiene with hydrogen bromide at room temperature, two isomeric products are isolated. Draw the structures for these isomeric products. Which is the kinetic isomer and which is the thermodynamic isomer.arrow_forwardSuppose you are told that each reaction is a substitution reaction but are not told the mechanism. Describe how you could conclude from the structure of the haloalkane, the nucleophile, and the solvent that each reaction is an SN2 reaction.arrow_forwardTreatment of propadiene (an allene) with hydrogen bromide produces 2-bromopropene as the major product. This suggests that the more stable carbocation intermediate is produced by the addition of a proton to Br HBr. H2C=C=CH, H3C CH2 a terminal carbon rather than to the central carbon. Propadiene 2-Bromopropene (a) Draw both carbocation intermediates that can be produced by the addition of a proton to the allene. (b) Explain the relative stabilities of those intermediates. Hint: Draw the orbital picture of the intermediates and consider whether the CH, groups in propadiene are in the same plane.arrow_forward
- Acid-catalyzed bromination of pentan-2-one (CH3COCH2CH2CH3) forms two products: BrCH2COCH2CH2CH3 (A)and CH3COCH(Br)CH2CH3 (B). Explain why the major product is B, with the Br atom on the more substituted side of the carbonyl group.arrow_forwardTwo substitution products result from the reaction between 3-chloro-3-methyl-1- butene with sodium acetate (CH3COO – Na +) in acetic acid under SN1. Identify the products.arrow_forwardH3C N- H₂NNH₂ H⭑ CH3 H3C IN CH3 Hydrazine reacts with 2,4-pentanedione to yield 3,5-dimethylpyrazole. Including protonations and deprotonations, the reaction takes 12 steps. Write out the mechanism on a sheet of paper and then draw the structure of the product of step 6. • You do not have to consider stereochemistry. •You do not have to explicitly draw H atoms. • Do not include lone pairs in your answer. They will not be considered in the grading. • In an elimination step, include the structure of the leaving group, but draw it in its own sketcher. Separate structures with + signs from the drop-down menu. ? Sn th Previous Nextarrow_forward
- The reaction of (S)-2-bromopentane with potassium cyanide to yield 2-methylpentanenitrile (2-cyanopentane) occurs due to a nucleophilic substitution pathway. The reaction is 100% stereospecific. Please explain what this observation tells about the mechanism of the reaction.arrow_forwardThe reaction of 1-bromopropane and sodium hydroxide in ethanol occurs by an SN2mechanism. What happens to the rate of this reaction under the following conditions?(a) The concentration of NaOH is doubled.(b) The concentrations of both NaOH and 1-bromopropane are doubled.(c) The volume of the solution in which the reaction is carried out is doubled.arrow_forwardCompounds X and Y are both C7H15Cl products formed in the radical chlorination of 2,4-dimethylpentane. Base-promoted E2 elimination of X and Y gives, in each case, a single C7H₁4 alkene. Both X and Y undergo an SN2 reaction with sodium iodide in acetone solution to give C7H15l products; in this reaction Y reacts faster than X. What is the structure of X? • Do not use stereobonds in your answer. • In cases where there is more than one possible structure for each molecule, just give one for each. . Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate structures with + signs from the drop-down menu. наarrow_forward
