Based on the balanced overall equation for the reaction, you performed in the lab. (CH3)3C-Cl + 2H2O ----------> (CH3)3C-OH +H3O+ +Cl- a) write three steps mechanism for the hydrolysis of tert-butyl chloride with water. show a curved arrow to represent the movement of electrons. b) label the arrow- determining step for this reaction.

In our experiment we will use three different substrates: 1°,
n-butyl chloride; 2°, sec-butyl chloride; and 3°, tert- butyl
chloride, and we will evaluate their reactivity and the rate of the
reaction in an SN1 reaction. We will use an acid-base indicator to
monitor the completion of the reaction and a salt, silver nitrate,
to obtain a precipitate. The success of the reaction is evidenced
by the change in color of the indicator (from orange to red) due to
the...

please help with questions 1 and 2.. thank you!
1. A reaction in a kinetics experiment is started when 4.00 mL of 0.100 M t-butyl chloride is mixed with solvent (diluted) to a final volume of 20.0 mL. After 65 sec, t1/no has been reached. a. What is the concentration of t-butyl chloride (molarity) at the start of the reaction? b. What is the value of the rate constant (k) if the reaction is first order? C. What is the...

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...
