- The following reaction has a ΔSsystem < 0 O2(g) → 2O(g) T or F can you explain why this is false?Please fill out for each reaction i.Fill in the missing starting materials, products, or reagents as necessary.If no reaction occurs, write "N.R." and explain why this is the case. ii. Label each transformation as SN1, SN2, or acid/base. iii. Indicate if the product is racemic or a single enantiomer.SN1 is always a competing reaction of E1. True or False?
- Draw the products of the SN1 reaction below and use wedge-and-dash bonds to indicate the stereochemistry of any stereogenic centers.i. Fill in the missing starting materials, products, or reagents as necessary. ii. Label each transformation as SN1, SN2, or acid/base. iii. Indicate if the product is racemic or a single enantiomerThe use of curved arrows is a powerful tool that illustrates even complex reactions. a.Add curved arrows to show how carbocation A is converted to carbocation B. Label each new σ bond formed. Similar reactions have been used in elegant syntheses of steroids. b.Draw the product by following the curved arrows. This reaction is an example of a [3,3] sigmatropic rearrangement, as we will learn in Chapter 25.
- What are the products from the following reactions? Please help with part e,f,gArrange the alkyl halides in order of increasing reactivity in an SN2 reaction with KI in acetone (least first). I, IV, III, II II, III, I, IV IV, I, III, II III, II, IV, IQ4 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.
- Draw the reaction products for each SN1 reaction and indicate the appropriate stereochemistry.Draw the SNl or SN2 reaction with CN for the following molecules t butylchloride , n - butylbromide , 2 -bromobutane . Explain in which mechanism it will react and why ?Based on your knowledge in biological chemistry reaction in biomolecules, what do you think is the best type and product for the above reaction? a. SN1 b. SN2 c. E1 d. E2 e. None of the above
