Example of a solvolysis Hydrolysis of tert-butyl bromide rate = k [alkyl halide] First-order kinetics implies a unimolecular rate-determining step Mechanism is called SN1 which stands for substitution nucleophilic unimolecular (1) Kinetics and Mechanism + Br – : :: unimolecular slowslow C CH3 CH3 CH3 Br : C H 3C CH CH3 + Mechanism
A SN1 Reaction: Synthesis of tert-Butyl Chloride
tert-Butanol reacts readily with HCl and forms the corresponding tert-butyl chloride at room temperature SN1 mechanisms are unimolecular because its slow step is unimolecular The reaction proposed involves an initial step where the tert- butyloxonium ion is formed by protonation

Hydrogen bromide in generated in situ according to the equation NaBr + H2SO4HBr + NaHSO4 Excess sulfuric acid is used and the mechanism involves the SN2 displacement of the protonated hydroxyl group (water) by bromide ion Water is the leaving group CH3CH2CH2CH2OH+HBr CH3CH2CH2CH2OH2+ Br CH3CH2CH2CH2OH2+ Br slow rate-determining step
How does tert-butanol react with HCl?
- tert-Butanol reacts readily with HCl and forms the corresponding tert-butyl chloride at room temperature. SN1 mechanisms are unimolecular because its slow step is unimolecular. The reaction proposed involves an initial step where the tert- butyloxonium ion is formed by protonation.
Is tert-butyloxonium ion unimolecular?
- The reaction proposed involves an initial step where the tert- butyloxonium ion is formed by protonation. This ion then dissociates to a second intermediate a carbocation - an ion that contains a positively charged carbon. Since only one species, tert-butyloxonium ion, undergoes a chemical change in this step, the step is unimolecular.
How to prepare primary alkyl bromide from primary alcohols?
- Primary alkyl bromides can be prepared from the corresponding alcohols by treatment with sodium bromide and sulfuric acid. Hydrogen bromide in generated in situaccording to the equation Excess sulfuric acid is used, and the mechanism involves the S N 2 displacement of the protonated hydroxyl group (water) by bromide ion.
How does tert-butylcation react with nucleophile chloride ion?
- The carbocation (tert-butylcation) being strongly electrophilic then reacts with the nucleophile chloride ion in a fast step originating thetert-butyl chloride final product – Scheme SM 2.1.1.1.3Since the nucleophile is not involved in the rate–determining step of the process a strong nucleophile is not important in this process.
