The overall yield (in %) for the following reaction sequence is ______________ 
To calculate the overall yield for the reaction sequence, we multiply the yields of each step. Given yields are:
Step 1: 90% = 0.90
Step 2: 80% = 0.80
Step 3: 80% = 0.80
Overall yield = 0.90 × 0.80 × 0.80
Let's calculate:
Overall yield = 0.90 × 0.80 = 0.72
Overall yield = 0.72 × 0.80 = 0.576
Convert 0.576 to percentage: 57.6%
The overall yield is 57.6%, which falls within the given range of 56% to 58%.
