- Organic solvents like benzene, ether, and chloroform are neither protic nor strongly polar. What effect would you expect these solvents to have on the reactivity of a nucleophile in SN2 reaction?arrow_forward1. Predict the elimination products of the following reactions. When two alkenes are possible, predict which one will be the major product. Explain your answers, showing the degree of substitution of each double bond in the products. 2. Which of these reactions are likely to produce both elimination and substitution products? (a) 2-bromopentane +NaOCH3 (b) 3-bromo-3-methylpentane +NaOMe(Me= methyl, CH3) (c) 2-bromo-3-ethylpentane +NaOH (d) cis-1-bromo-2-methylcyclohexane +NaOEt (Et= ethyl, CH2CH3)arrow_forward1 mol NH3 + 1 mol C2H5Cl when heated there is a lot of unreactd NH3 (about 80%). Why does this occur? How do nucleophiles and electrophiles play a role in this?arrow_forward
- Why does CH 2 CHCHBrCH 3 undergo solvolysis much more rapidly than 2-bromobutane?arrow_forwardBriefly explain why direct hydrogenation (H2/Pt) cannot be utilized to partially reduce an aromatic ring.arrow_forwardFollowing is a balanced equation for the allylic bromination of propene. CH2==CHCH3 + Br2 h CH2==CHCH2Br + HBr (a) Calculate the heat of reaction, H 0, for this conversion. (b) Propose a pair of chain propagation steps and show that they add up to the observed stoichiometry. (c) Calculate the H 0 for each chain propagation step and show that they add up to the observed H 0 for the overall reaction.arrow_forward
- Following is a balanced equation for bromination of toluene. (a) Using the values for bond dissociation enthalpies given in Appendix 3, calculate H0 for this reaction. (b) Propose a pair of chain propagation steps and show that they add up to the observed reaction. (c) Calculate H0 for each chain propagation step. (d) Which propagation step is rate-determining?arrow_forward5- In the Wittig reaction, the lide reacts with an aldehyde to form an alkene. Which of the following best describes the stereochemical outcome of a Wittig reaction when using a stabilized ylide?Produces exclusively E-alkenes.• Produces exclusively Z-alkenes.Produces a mix of Z- and E-alkenes, with Z being the major product.Produces a 50:50 mixture of Z- and E-alkenes) Produces a mix of Z- and E-alkenes, with E being the major product. 4- For the synthesis of ethyl 4-chlorocinnamate via the Wittig reaction, which of the following statements is true regarding the mechanism?O The ylide donates a proton to the aldehyde, directly forming the alkene withoutany intermediates.The ylide forms a stable complex with the aldehyde, which is then reduced toform the alkene.The reaction proceeds through a direct displacement mechanism, where the ylide replaces the aldehyde's oxygen.© The phosphonium ylide attacks the carbonyl carbon, forming a betaine intermediate that undergoes rearrangement to…arrow_forwardQ: Provide the reagents needed to carry out the reactions below (or the product obtained). If two steps are needed, clearly indicate 1. (reagent A); 2. (reagent B). If separate steps are not indicated, I will assume you mean that all reagents are introduced together. Will H20 and H30+ work if so can you explain how for this question I am working on 2Earrow_forward
