6) During the Wittig reaction, you perform the reaction as follows:4-chlorobenzaldehyde (136 mg) and (carbethoxymethylene)triphenylphosphorane(323 mg) were placed in a 25 mL Erlenmeyer flask. The two solids were mixed vigorously for 15 min. The reaction mixture was diluted with hexanes (2.9 mL - density 0.661 g/mL) The by-product, triphenylphosphine oxide, was filtered off.0.085 g total of triphenyl phosphine was isolated. The filtrate was then evaporated to dryness to obtain 0.151 g of the desired product, pure ethyl-4-chlorocinnamate, as a colorless oil.What is the % effective mass yield of the reaction? (Your result should be reported as a % value and rounded to the nearest integer.
