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( 2-phenylethyl)anthracene or trans -9-2( 2-phenylethyl)anthracene Please explain how you know and found using the values given. Lastly, the TLC performed is lab, interpret the TLC and state if your reaction was successful and how do you know. For the TLC, Spot A is the (benzyltriphenylphosphonium chloride). Spot B is (benzyltriphenylphosphonium chloride and product 9-(2-phenylethenyl)anthracene, Spot C.is just product 9-(2-phenylethenyl)anthracene, Spot D is 9-anthraldehyde and product 9-(2-phenylethenyl) anthracene, SPOT E is just 9-anthraldehyde. Please explain if the TLC is successful or not. Please answer this question completely so I can understand it, it's one reaction with multiple parts thank you!

Part A of experiment:
Working in the fume hood, combine 4.0 mL of 10% NaOH solution
and 4 mL EtOH in a 50 mL round bottom flask.
Dissolve 1.0 mL (8.6 mmol) of acetophenone into your
solution.
Add 1.0 mL (9.8 mmol) of benzaldehyde and a magnetic stir bar to
your flask. Clamp the flask
above a stir plate.
Monitor the reaction for 45 minutes by TLC. Acetophenone needs
to be diluted prior to TLC, and
cannot be spotted neat....

Thank You!
In early April 2017, United Airlines (United), one of the largest airlines in the world, found itself yet again in the middle of a service disaster this time for forcibly dragging a passenger off an overbooked flight.
