Chemistry 31.1 FG-1L 2BSFT Group 1 Viena G. Monterde February 3, 2014 EXERCISE 8 Synthesis of tert-Butyl Chloride ABSTRACT Alkyl halides can be prepared by acid catalyzed substitution reactions of alcohols. SN1 and SN2 are the pathways that compounds can follow. In SN1 mechanism, the rate-determining step is where the alcohol gets protonated following water loss. The second step is the attack of the nucleophile on the carbocation. The experiment aims to prepare tert-Butyl chloride from tert-Butyl alcohol using hydrochloric acid by SN1 mechanism. The calculated percent yield is 12.15%. The low yield can be due to the excessive calcium chloride which caused the desired compound to adhere to it, thus lowering the volume of the final product. The experimental boiling point of tert-butyl chloride (TBC) is 50.5°C while that of tert-butyl alcohol (TBA) is 80.5°C. They did not coincide with the theoretical boiling points of TBC and TBA—82.2°C and 52°C respectively. This can be due to the error within the apparatus itself, inconsistent judgement in monitoring the temperature or the external pressure of the environment where it was conducted....
