A particular pharmaceutical drug requires four reactions, back to back, to synthesize in a lab. You perform each of the four reactions, and obtain the percent yields for each reaction as shown below. If the percent yield for the overall multistep synthesis is 21.6%, what was the percent yield of reaction 4? Reaction 1: 81.5% yield Reaction 2: 71.9% yield Reaction 3: 96.4% yield Reaction 4: ?
