4026 synthesis of 2-chloro-2-methylpropane (tert-butyl chloride) from tert-butanol oh cl c4h10o c4h9cl h2o (365) (741) (926) + + hcl classification reaction types and substance classes nucleophilic substitution chloroalkane, alcohol work methods stirring with magnetic stir bar, column distillation, filtering, use. Synthesis tert-butyl chloride is produced by the reaction of tert-butyl alcohol with hydrogen chloride in the laboratory, concentrated hydrochloric acid, is used the conversion entails an sn1 reaction as shown below. Carbocations formed from using hydrohalic acids may rearrange for tertiary, because the resulting carbocations are unlikely to rearrange, hydrohalic acids are effective halogenating agents in this experiment, you will be converting t- butyl alcohol to t-butyl chloride using concentrated hydrochloric acid oh h3c h3c h3c. Objectives: 1 to produce tert-butyl chloride from tert-butyl alcohol 2 to understand the sn1 and sn2 mechanism involved in the reaction 3 to determine the yield of percentage of t-butyl chloride introduction: alkyl halide is also known as haloalkane or halogenalkane alkyl halide is a hydrocarbon group. The preparation of tertiary butyl chloride (2-chloro-2-methylpropane) [sn1] (ch3 )3c-oh + h+ → (ch3)3c-+oh2 → (ch3)3c+ + cl- → (ch3)3c-cl tertiary alcohol carbocation alkyl halide introduction this preparation illustrates the fast reaction of a tertiary alcohol with hydrogen chloride to give the.

The generalized mechanism for each of these reaction types has been depicted below, using tert-butyl chloride as the starting material: notice that the product of an sn1 (the reader may recall that, e2 reactions are frequently used in synthesis, in sharp contrast to e1 reactions) the proportion of the starting material that. Tert-butyl chloride is a colorless, liquid organic compound at room temperature it is sparingly soluble in water, with a tendency to undergo spontaneous solvolysis when dissolved into it the compound is flammable and volatile, and its main use is as a starting molecule to carry out nucleophilic substitution.
