- Please complete both subpart reactions in clear handwritten answer on a paper!I had written those notes above the nucleophiles, so I am unsure if they are correct.Step 2 of the iodination of benzene shows water acting as a base and removing a proton from the sigma complex. We did notconsider the possibility of water acting as a nucleophile and attacking the carbocation, as in an electrophilic addition to an alkene.Draw the reaction that would occur if water reacted as a nucleophile and added to the carbocation. Explain why this type ofaddition is rarely observed.
- Rank the following species from best nucleophile to poorest nucleophile in an aqueous solution:Amides are weak nucleophiles but their conjugate bases are string nucleophiles. The amide drawn below can be deprotonated in four possible locations, labeled A-D but two are considerably more acidic than the others. Draw the two different Bronsted Lowery acid/base reactions (using HO- as the BL base) showing the deprotonation at these two locations. Draw all RS with arrows for both conjugate bases but no hybrids. Based on your resonance analysis which location is the most acidic in the molecule? Why is it most acidic? Amides can also be protonated by a strong acid in two different locations. Draw two different conjugate acids for the amide above as well as RS with arrows for each. Based on your resonance analysis which atom is the most basic in an amide?I. Of the following reactions, answer what is requested:a) Analyze the type of alkyl halide and determine if the nucleophile is strong or weak and also if it has a basic character.b) According to the previous paragraph, determine if there is competition between the substitution and elimination reactions.c) Describe the mechanism of each of the product (s) that are formedd) Of the product (s) that are formed, indicate which one comes from the substitution reaction and which one from eliminatione) If two or more products are formed, indicate which would be the majority and explain why.
- Using the attached molecule and synthesis, please redraw the molecule showing the stereochemistry attained through the synthesis.The product in this reaction is basic enough to be protonated by a dilute HCl solution. Draw the protonated species, clearly showing where protonation occurs. Draw all possible resonance structures of the conjugate acid of the product, and use these to explain why the product is so much more basic than a typical ester, like ethyl acetate.Label the reactive features of the following reactants, select the most reactive feature, thenwrite and highlight what it needs. Also, state if a carbocation, carbon radical, or carbanion willstart to develop, and/or if aromatic character will be lost as a result of a reaction between thesemolecules.(E)-4,5-dimethyloct-4-ene + HBr and H2O2
- In the chemical reaction between benzyl chloride 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 within this 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.Label the reactive features of the following reactants, select the most reactive feature, thenwrite and highlight what it needs. Also, state if a carbocation, carbon radical, or carbanion willstart to develop, and/or if aromatic character will be lost as a result of a reaction between thesemolecules. cyclohexanone + 2 equivalents of methanol with acidFor each of the following, write the major product(s) and then draw out each step in the mechanism using curved arrows. Show ALL lone pair electrons and formal charges. Redraw ALL molecules as to show explicitly ALL bonds being broken or formed. Identify the molecular orbital (HOMO) of the nucleophile and the molecular orbital (LUMO) of electrophile involved in the nucleophilic attack. MO diagrams are not necessary..
