2. Explain the following questions regarding the possible
contamination of the final isolated product with dicyclopentadiene
(the cyclopentadiene dimer).
a. Since “cracked” cyclopentadiene can spontaneously dimerize
back to dicyclopentadiene, could the dimer be formed as an unwanted
“by-product” during the experiment?
b. How does the experimental procedure minimize contamination of
the final isolated (desired) product with this (undesired)...
