question
If the Diels-Alder reaction is classified as a [4 + 2] cycloaddition reaction, how would you classify the cycloaddition reactions shown below? You are instructed to use 140 mg of cyclopentadiene (d = 0.80 g/mL). It is typically more convenient to measure out a volume of liquid. What volume of cyclopentadiene should be used? In the Diels-Alder reaction that you will be...
