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
A SN1 Reaction: Synthesis of tert-Butyl Chloride
A mechanism involving cleavage of the acyl?oxygen bond is mostcommon and is observed for all simple esters tert-Butyl esters however react through adifferent mechanism involving scission of the alkyl?oxygen bond in the rate-determining step Acid-catalysed hydrolysis reactions are reversible
Determination of the Order Rate Constant Half-Life and
We will determine the order of the reaction for t-butyl bromide by monitoring the t-BuBr concentration remaining at various times in the reaction As the hydrolysis reaction proceeds the amount of remaining t-BuBr will constantly diminish As there is less reactant the reaction will slow

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.
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.
What if t-butyl-chloride was erroneously added to the reaction mixture?
- It is worth pointing out thatan excess amount of t-butyl-chloride was erroneously added to the reaction mixture (0.50 mL instead of 0.35mL), but NMR analysis suggests that the quantity of this excess reagent in the ?nalproduct is negligible (and, in fact, it may have increased the yield of our ?nal product byproviding more reagent to react).
What is the mechanism of conversion of tertiary alcohols to alkyl?
- This type of mechanism does not occur with tertiary substrates, however, the substitution of the tertiary alcohol can occur by a unimolecular mechanism (SN1) with formation of a carbocation resulting in a mixture of stereoisomers.
