Results After evaluating our chromatography graph, we determined that the chlorine alkyl halide formed more of the final product. These results differ from the lab manual. Our lab manual states that nucleophilic ability will increase as you go down a column on the periodic table. Considering this statement, we would believe that the nucleophilic ability of bromine would be greater than chlorine, thus, forming more of the bromine alkyl halide product. This unexpected result could have been caused by inaccurate transfer of the products in the conical vial, which could have resulted in not transferring all of the alkyl bromide into the conical vial. Using the Excel software, we were able to view our chromatography graph, which showed two peaks, representing the retention time of each alkyl halide. The alkyl chloride had an area of 490.24 and the alkyl bromide’s area was 385.73. 2-Chloro-2- methylpropane made up about 56% of the total area. 2-Bromo-2-methylpropane made up 44% of the total area.
