Using physical density constant, the volume of 2-methyl-2-butanol was first converted into grams of alcohol. The grams were then converted into moles of alcohol using its molecular weight. Using the reaction stoicheometry, the moles were then converted into moles of chloride (product). Finally knowing the molecular weight of the product allowed to convert grams into moles. Calculating mass of 2-methyl-2-butano. One way to get a better percent yield is by minimizing transfers. A low percent yield could be a result of evaporation and incomplete reaction. The reaction could have been interrupted and some molecules deviated towards secondary products thus generating impurities. These are errors that are hard to control and are important to consider in the final evaluation. The large difference in percent yield was probably a result of poor separation technique or perhaps layers weren’t completely settled at the time of physical separation. Conclusion Overall, the experiment succeeded in synthesizing an alkyl halide from a tertiary alcohol.

The presence of tertiary alkyl halide was determined by reacting a small amount of the synthesized product with a solution of silver nitrate in ethanol. Tertiary alkyl halide rapidly reacted with AnNO3 to form a precipitate of AgCl solid. Some difference existed between the actual and theoretical percent yields as a result of some errors. These differences, however, can be accounted for by experimental error.
