Interpretation:
Reactants X and product Y in the given sequence of reactions is to be determined.
Concept Introduction:
Alkyl sulfonates are prepared by the reaction of an alcohol with sulfonyl chlorides. These reactions are carried out in suitable solvents such as trimethylamine,
In these reactions, the hydrogen atom of the hydroxyl group in alcohols is substituted by the methyl sulfonate group.
Their preparation comprises the oxygen of the alcohol and not the carbon to which the oxygen is attached.
The stereochemistry of the original alcohol and the carbon skeleton both are maintained when the alcohols are converted to their corresponding alkyl sulfonates.
If the structure for the product molecule is known, the corresponding reactant alcohol can be found by replacing the methyl sulfonate group by the hydrogen atom without changing the stereochemistry of the alcohol molecule.
The reaction of this methane sulfonate with sodium azide produces the corresponding alkyl azide, and this reaction follows the

- Under second-order conditions (strong base/nucleophile), SN2 and E2 reactions may occur simultaneously and compete witheach other. Show what products might be expected from the reaction of 2-bromo-3-methylbutane (a moderately hindered 2°alkyl halide) with sodium ethoxide.arrow_forwardWorking Backwards Parte Deux. a.First, identify which functional groups changed during the reaction. Did stereochemistry change too? b. Based on your answers to A and B, what kind of reaction occurred here, SN1 or SN2? c.Suggest reagents and solvent that could accomplish this reaction.arrow_forwardodine monochloride, ICI, is a reagent whose reactivity mirrors that of other dihalogens (X₂) with nucleophilic πt bonds. Using curved arrows to show the flow of electrons, draw a plausible mechanism for the following transformation. Make sure that your mechanism accounts for the correct stereoselectivity.arrow_forward
- 1. In which of the following tests/reagents would cyclohexene and hexane both yield a positive result? I. t-BuCl in AlCl3 II. Br2 in light III. Halogenation by I2 in KI IV. KMnO4 2. Which of the following is statements is/are TRUE about the experiment on the relative rates of electrophilic aromatic substitution?I. The experiment must be performed in dark conditions. II. Using the same solvents, a faster decolorization will be observed in aniline as compared to ethylbenzene. III. Chlorobenzene will react faster than methoxybenzene. IV. The use of AlCl3 in the halogenation of aromatic compounds using elemental bromine could hasten the reaction.arrow_forwardProvide the necessary sequence of reactions to generate the products below from their respective starting materials.arrow_forwardUnder 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-methyl butane (a moderately hindered 2∘ alkyl halide) with sodium ethoxide. Do not worry about stereochemistry in the SN2 product for this problem. Don't forget about stereochemistry.arrow_forward

Describe how you could conclude from the structure of the haloalkane, the nucleophile, and the solvent that each reaction is an SN2 reaction.arrow_forwardPropose a product structure that could be formed from the reaction below and provide an arrowed mechanism to support the process of formation for the product.arrow_forward
- we know that ethers, such as diethyl ether and tetrahydrofuran, are quite resistant to the action of dilute acids and require hot concentrated HI or HBr for cleavage. However, acetals in which two ether groups are linked to the same carbon undergo hydrolysis readily, even in dilute aqueous acid. How do you account for this marked difference in chemical reactivity toward dilute aqueous acid between ethers and acetals?arrow_forwardShow with examples and structures the Order of Reactivity in SN2. 2- Show Some SN2 Reactions With Bromo-Ethane.

Attempts to prepare a similar mixture of these same isomeric products (propylthiocyanate and propylisothiocyanate) starting from 1-propene is illustrated below. Despite the strong acidity of thiocyanic acid (recall pKa = 1.1), this addition reaction does not lead to either of the products indicated.
