- Consider the following statement in reference to SN1, SN2, E1, and E2 reactions of haloalkanes. To which mechanism(s), if any, does the statement apply? Involves a carbocation intermediatearrow_forwardb) Explain in detail what characteristics of the alkyl halide influence whether a mechanism will be SN1 or SN2. c) Explain in detail what characteristics of a nucleophile influence whether a reaction will be SN1 or SN2.arrow_forwardFor an SN1 reaction, which of the following is the correct order from the given statements below: (1) The nucleophile attacks both from the front and from the back of the planar carbocation. (II) The nucleophile attacks from a backside position. (II) The halide ion as the leaving group leaves initially. (IV) The halide ion as the leaving group leaves subsequently. (V) The halide ion as the leaving group leaves simultaneously as the nucleophile approaches. (VI) The product is formed. (VII) A stable carbocation is formed. (VIII) A product with inversed chirality is formed. Nu R-C-X + R-C-Nu wharrow_forward
- (b) Consider the reaction of 1-bromobutane with a large excess of ammonia (NH3). Draw the reactants, the transition state, andthe products. Note that the initial product is the salt of an amine (RNH3+ Br - ), which is deprotonated by the excess ammonia to give the amine.arrow_forwardConsider the following statement in reference to SN1, SN2, E1, and E2 reactions of haloalkanes. To which mechanism(s), if any, does the statement apply? Order of reactivity of haloalkanes is 3°> 2°> 1°.arrow_forwardFor the following sets of substitution reactions that occur via an SN2 mechanism, draw the main organic substitution product (i.e., not the leaving group, for each reaction draw the product, though the products may be equivalent) and indicate which reaction occurs at the faster rate. (a) H3C CH₂O H3C E H3C Br (b) Br CH3O H3C + H3C-Br CH3O- H3C-Brarrow_forward
- Please give the main substitution product for each of the following reactions, and indicate the dominant mechanism: (a) 1-bromopropane + NaOCH3 → (b) 3-bromo-3-methylpentane + NaOC2H5 →arrow_forwardLabel the following as: SN1, SN2, E1, E2 reactions. Create examples with drawn mechanisms.arrow_forwardIn the addition of bromine to cyclohexene in ether, which of the following statements are true? Choose all that apply. A) The reaction must occur in two steps for a trans product to be formed. B The reaction must be concerted for a trans product to be formed. (C) Br must add first as an electrophile and then bromide must add second as a nucleophile. D Bromide must add first as a nucleophile and then Br must add second as an electrophile.arrow_forward
- Consider two SN1 reactions: (A) water and tert-butylbromide and, (B) water and 2- bromopropane, both having the same concentration of reactants. which reaction will be faster Draw an energy vs. reaction coordinate diagram showing only the rate-determining step for both reactions on the same set of axes (assume potential energies are the same)arrow_forwardA problem often encountered in the oxidation of primary alcohols to acids is that esters are sometimes produced as by-products. For example, oxidation of ethanol yields acetic acid and ethyl acetate: Propose a mechanism to account for the formation of ethyl acetate. Take into account the reversible reaction between aldehydes and alcohols:arrow_forward11.; (a) Similar to alkanes, hydrogen gas can undergo radical bromination according to the reaction below. Propose a chain-reaction mechanism for this reaction, including an initiation step, propagation steps, and two plausible termination steps. The homolytic bond dissociation energy for Br-Br is 46 kcal·mole', for H-Br is 88 kcal'mole and for H-H is 104 kcal'mole'. hv H-H + Br-Br 2 H-Br (b) Calculate the overall AH for the above propagation steps (show all work).arrow_forward
