compound
The IR frequencies for compound cis-norbornene-5 6-endo-dicarboxylic anhydride can be assigned as follows-
Two signals 1838 and 1759 cm-1 are signature peaks confirming the presence of anhydride moiety.
Signals around 3000 cm-1 and 2900 cm-1 confirms possibilty of -C-H/=C-H stretches.
Presence of several strong stretches in fingerprint region of 1250-1050 indicates the presence C-O-C framework.

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)...
