indicates that there was no side reactions‚ as none of the side product was retrieved. Liquid distill at about 82.8°C‚ which indicates that 2-chloro-2-methylbutane was the only product of this reaction. The theoretical yield was calculated using 2-methyl-2-butanol as the limited reagent in the reaction‚ and was found to be 7.80 grams of 2-chloro-2-methylbutane. The experimental yield that was retrieved was found to be much less‚ at 1.84 grams. The percent yield was calculated to be 23.60% utilizing

Eidell October 24‚ 2014 Preparation and IR Analysis of 2-chloride-2-methylbutane Line Reaction Abstract The purpose of this experiment was to react 2-methyl-2-butanol with concentrated HCl in order to form 2-chloride-2-methylbutane. The hydrogen for the HCl make the -OH from the 2-methyl-2-butanol into a good leaving group because H2O is formed. The H2O leaves and Cl- is free to bond with the carbocation creating 2-chloride-2-methylbutane. The materials needed for the lab were an Erlenmeyer
