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...

A)
B)
Complete the drawing of the product of the Diels-Alder reaction, ignoring stereochemistry. The Diels- Alder reaction between butadiene and dimethyl maleatc yields a ring structure, as shown in the product below Complete the structure by drawing any missing bonds and indicating the stereochemistry of the new stereocenters.
