- For SN1 Explain if 3o ( tertiary) alkyl halides reacted (fastest or slowest) explain why. Be sure to explain if alkyl halides did not react or did react and why. 3o (tertiary) compounds listed are: 2-chloro-2-methylpropane (see picture) Base your explanations on the following considerations: the nature of leaving group, the effect of structure, steric hindrance and any other feature.Can someone explain the answers to 28, 29, and 30? The answers are B, A, A. I understand lindar catalyst makes cis alkenes and Na/NH3 makes trans alkenes but I dont understand how the second step of Br2, OsO4 influences the stereochemistry between the 2 . Will rate quickly if helpful. Thanks!Draw the molecule: Under second-order conditions (strong base/nucleophile), SN2 and E2 reactions may occur simultaneously and compete with each other.Show what products might be expected from the reaction of 2-bromo-3-methylbutane (a moderately hindered 2∘∘ alkyl halide) with sodium ethoxide. Do not worry about sterechemistry inther SN2 product for this problem. Don't forget about stereochemistry.
- In the chemical reaction between 1-Bromobutane and ethanolic silver nitrate solution, a precipitate is barely formed. Using the skeletal structures of the molecules, write out the skeletal structure of each reaction (don't include the mechanism). Identify what the nucleophile is in each type of reaction, especially the SN1 reaction. Explain the reactivity of each electrophile/substrate in terms of whether they are tertiary, secondary, primary, etc. for each reaction. Include the overall chemical reaction.Assume that 2-chloropropane reacts with CN− in an SN2 reaction. Use the JSME editor () to draw the structure of the substitution product of the reaction. The guide on how to draw your structure can be found here Important Note: When drawing the structures in the JME editor please adhere to the following formats: 1. If the nucleophile is OH−, DO NOT manually add the "H" to the final product 2. If the nucleophile is CN−, be sure to include the appropriate bonding between the C and N in the final productMethylating agents are substrates that deliver methyl groups to nucleophiles, and so are themselves electrophilic. What is the most common methylating agent (a) in the laboratory and (b) in biological systems? Discuss their similarities and differences... Solve it asap
- Q4 Which statement below about Sn1 reactions is incorrect? (A) SN1 reactions are stepwise and have intermediates. (B) The slow step in a SN1 reaction is formation of the carbocation intermediate. (C) SN1 reactions have first order kinetics which means only the alkyl halide is involved in the rate limiting step. (D) The products of a SN1 reaction will be a pair of enantiomers. (E) An aprotic solvent is best for Sn1 reactions as they tend to help stabilize carbocation intermediates.Why we need step 3 before step 4? a. Because the nitro group increases the electrophilicity at the ortho positions which is where the bromine is added. b. Because the amine group is a strong ortho, para director which is what controls the regiochemical outcome of this bromination. c. Step 4 is unessesary. The symmetry of compound 3 allows for the bromination to be regioselective and give compound 5. 5. There will be a mixture of products because there is no selectivity for a major product.1. Which of the following is the strongest nucleophile? Refer to the diagram below with an MeOH, MeSH, etc. 2. Which of the following is true about the stereochemistry of SN1 reaction?a.retention of configuration at the electrophilic centerb.50:50 mixture of retention and inversion of configuration at the electrophilic centerc.inversion of configuration at the electrophilic centerd. slightly more inversion than retention at the electrophilic center
