The integrated areas of the selected multiplets in the spectrum are as follows: δ1.0, 2 units, δ1.1, 9 units, δ1.6, 32 units, δ3.6, 26.8 units, δ3.7, 26.8 units, δ4.0, 3.3 units, δ5.8 (a triplet not visible in the spectrum), 0.7 units. based on your assignments the integration data, calculate the approximate percentage of each isomer present in the mixture. explain your determination as completely as possible.
