Experiment 5.49 t-BUTYL CHLORIDE (2-Chloro-2-methylpropane) Me3COH + HC1 -------- Me3CCl + HzO... 

The order of SN2 reactivity is primary > secondary > tertiary, and branching of the chain close to the site of substitution hinders reaction. The unbranched primary halide n-butyl chloride will be the most reactive and the tertiary halide tert-butyl chloride the least. The order of reactivity will therefore be 1-chlorobutane > l-chloro-2-methylpropane > 2-chlorobutane > 2-chloro-2-methylpropane. 

The rate of solvolysis or de-hydrochlorination of /-butyl chloride (2-chloro-2-methylpropane) has been studied very extensively under standardized conditions, and the rate constant has been used as a characterization of solvent polarity. The reaction proceeds according to the scheme ... 

Free energy versus REACTION PROGRESS DIAGRAM FOR THE SN I REACTION OF TERT-BUTYL CHLORIDE (2-CHLORO-2-METHYLPROPANE) AND ACETATE ANION. 

Since reaction rates can be strongly affected by solvent polarity cf. Chapter 5), the introduction of solvent scales using suitable solvent-sensitive chemical reactions was obvious [33, 34]. One of the most ambitious attempts to correlate reaction rates with empirical parameters of solvent polarity has been that of Winstein and his co-workers [35-37]. They found that the SnI solvolysis of 2-chloro-2-methylpropane (t-butyl chloride, t-BuCl) is strongly accelerated by polar, especially protic solvents cf. Eq. (5-13) in Section 5.3.1. Grunwald and Winstein [35] defined a solvent ionizing power parameter Y using Eq. (7-13),... 

Analogous reactions are used to manufacture sec-butyllithium and ferf-butyl-lithium using 2-chlorobutane (scc-butyl chloride) and 2 chloro-2-methylpropane (fert-butyl chloride), respectively, as shown in eq 4.13 and 4.14 ...
