2. The addition of HBr to 2-methylpropene can, in principle, give either 1-bromo-2- methylpropane or 2-bromo-2-methylpropane. In reality, only the latter is formed. Show mechanisms for the formation of each of these alkyl bromides, using curved arrows to indicate the flow of electron pairs. Also, construct reaction energy diagrams that describe the energy of the system as a function of the progress in formation of both alkyl bromides. Use these reaction coordinate diagrams to explain why 2-bromo-2-methylpropane is the only...

The sec-butyl cation can react as both a Lewis acid and a Brønsted- Lowry acid in the presence of a water-sulfuric acid mixture. In each case, however, the product is different. The two reactions are: 2. H2o +H3O+ a. In which reaction does this cation react as a Lewis acid? In which does it react as a Brønsted-Lowry acid? b. Write Lewis structures for reactants and products and show by...

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 SNI (substitution, nucleophilic, unimolecular) and S 2 (substitution, nucleophilic, bimolecular). Tertiary alcohols follow the Syl route, primary alcohols follow the Sy2 route, and secondary alcohols can follow either path. Under acidic conditions, the mechanism (Figure 1) of the Syl reaction involves rapid protonation of the alcohol, followed by...
