8) Draw a mechanism with all the proper arrows for the reaction from this experiment. Introduction Alkyl halides can be prepared from alcohols by reactions with hydrogen halides (HCI, HBr, or HI) via nucleophilic substitution. In this type of reaction, the nucleophile displaces a leaving group from a carbon atom of an organic substrate (here the alcohol once protonated). Both electrons of the new bond to the carbon are provided by the nucleophile while the leaving group departs with both...
13 SN1: Synthesis of tert-Butyl Chloride Alkyl halides can be prepared from their corresponding alcohols via an acid catalyzed substitution reaction. The mechanism of these acid catalyzed substitution reactions are labeled as Syl (substitution, nucleophilic, unimolecular) and S2 (substitution, nucleophilic, bimolecular). Tertiary alcohols follow the Snl route, primary alcohols follow the S2 route, and secondary alcohols can follow either path. Under acidic conditions, the mechanism (Figure 1) of the Sul reaction involves rapid protonation of the alcohol, followed by the...
please answer these questions 1: Which of the following is true for the reaction of (1R, 2R)-1-tert-butyl-1-fluoro-2-methylcyclohexane with potassium hydroxide? a: The product is (E)(6R)-1-tert-butyl-6-methyl-1-cyclohexene b: The product is (Z)(6R)-1-tert-butyl-6-methyl-1-cyclohexene c: The product is (Z)(6S)-1-tert-butyl-6-methyl-1-cyclohexene d: The product is (E)(6S)-1-tert-butyl-6-methyl-1-cyclohexene 2: Which of the following is not true for regioselective reactions? a: Generally, the selectivity lies to toward the Saytzeff product in elimination reactions. b: In a regioselective reaction, there is one product that predominates. c: The transition states of...
4) Can you ever have only SN2 or only SN1? Introduction Alkyl halides can be prepared from alcohols by reactions with hydrogen halides (HCI, HBr, or HI) via nucleophilic substitution. In this type of reaction, the nucleophile displaces a leaving group from a carbon atom of an organic substrate (here the alcohol once protonated). Both electrons of the new bond to the carbon are provided by the nucleophile while the leaving group departs with both electrons of its bond to...
10) Provide the results of the silver nitrate test. Introduction Alkyl halides can be prepared from alcohols by reactions with hydrogen halides (HCI, HBr, or HI) via nucleophilic substitution. In this type of reaction, the nucleophile displaces a leaving group from a carbon atom of an organic substrate (here the alcohol once protonated). Both electrons of the new bond to the carbon are provided by the nucleophile while the leaving group departs with both electrons of its bond to the...
3) Name two solvents that are commonly used for SN2 reactions. because they considerably slow down SN1 reactions. Introduction Alkyl halides can be prepared from alcohols by reactions with hydrogen halides (HCI, HBr, or HI) via nucleophilic substitution. In this type of reaction, the nucleophile displaces a leaving group from a carbon atom of an organic substrate (here the alcohol once protonated). Both electrons of the new bond to the carbon are provided by the nucleophile while the leaving group...
Given that the SN2 mechanism requires the nucleophile to force out the leaving group, what would you expect the product ratio of alkyl bromide to alky chloride be when sulfuric acid is the solvent? Also given that the SN1 mechanism requires the nucleophile to react with an empty p orbital of a carbocation involving bond formation, what would you expect the product ratio of alkyl bromide to alky chloride be when sulfuric acid is the solvent? R-Br > R-Cl or...
