This is the Wittig reaction. Below I have the reaction
performed. So first we have the IR of starting material and then
the product, all the peaks for all IR. Please identify the peaks in
all the IR. Please also explain the difference observed thank you!.
For this reaction an NMR is also performed, have to label the H NMR
based on the product formed also based on the values given have to
determine if the product was cis -9-2(...

Based on the Wittig Reaction exp. below, please answer a) and
b). In b) you can disregard the part about the IR, just please
interpret and assign protons, shift values, which protons are for
which groups, etc on the HNMR. The % yield was 34%, and MP was
lower than expected (to assist with answering part a). This should
be all the information you need to answer the question.

What is the objective of this experiment?
The reaction solvent for this experiment is xylene. What
property of this solvent makes it a better choice than toluene or
benzene?
Draw the orbitals involved in the 4+2 electrocyclization for
this reaction. Draw the structures of the reactants as best you
can. It may be appropriate to abbreviate the structure of
anthracene.
