Discussion In this experiment, the synthesis of p-di-tert-butyl benzene was achieved by using the Friedel-crafts Alkylation. How the purposes were or were not accomplished For this experiment, 0. 02356 grams of p-di-tertbutyl benzene were recovered. The theoretical percent yield was 0. 616 grams of the product. This gives a 38. 2% yield. The product obtained…
