A student runs the oxidation reaction of 2-hexanol, using 4.5 g of starting material and Oxone as the oxidant. After the reaction, the student is happy to obtain 4.1 g of crude product; however, after distillation only 2.2 g of 2 hexanone is obtained. Calculate the theoretical yield, the % yield of the crude and pure product, and the % recovery in the distillation step.
