A student weighed out 0.438 g anthracene and dissolved it in 5.14 mL xylene. They then added 0.269 g maleic an hydride, fit the flask with a reflux condenser and let the reaction reflux for 30.9 min. They isolated 0.582 g of product crystals. What was their percent yield? Type your answer rounded to the first decimal place (ex NN.N) without units or a percent sign.

A) A student weighed out 3.52 g. of salicylic acid in a 100 mL flask and adds 2.3 mL of acetic anhydride (density= 1.080 g/mL). Determine the maximum(theoretical) number of grams of acetylsalicylic acid she can prepare. B) If the student obtained 4.21 g. of aspirin, calculate the % yield. Briefly, explain why she might have obtained this amount of product.

In this Diels-Alder reaction, what is the limiting reagent for
this reaction? Please show work
In this experiment, a Diels-Alder reaction will be performed to generate 4-cyclohexene- 1,2-dicarboxylic anhydride. The reaction occurs when 1,3-butadiene is combined with maleic anhydride and heated as shown below. Once the product has been isolated, the IR spectrum, melting point, and experimental yield can be determined. 5.- I111NI O Due to the inherent difficulties with the handling of gaseous 1,3-butadiene, it will be generated in...

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.

The Diels-Alder Reaction of Anthracene with Maleic Ankydride The Diels-Alder reaction is a member of a class of reactions called cycloadditions. The reaction involves threex bonds, two from the dicne and one from the dienophile in a concerted reaction to form a six-membered ring. Since the reaction involves four n clectroes in the dicne and twor clostrons from the dienophile,...

You weighed out 0.3267 g of steel and completely dissolved it in 6 M nitric acid upon heating in the fume hood for an hour. The entire contents were transferred to a 250 mL volumetric flask, which was diluted to the mark with DI water. 10 mL aliquots were transferred to six different 250 mL Erlenmeyer flasks. To each Erlenmeyer flask, 5 mL of 85 % H3PO4 were added along with 0.4 g of KIO4. Increasing volumes, Vs of 0,...

Experiment Write Up Proposal You will write up a synthesis procedure for one reaction that could be potentially run in a face- to-face Chem 2321 lab session. Your proposal will include an introduction and procedure. The procedure will include step-by-step instructions for running the reaction (including reaction monitoring), work-up. (product isolation and purification), and analysis (characterization). You will need to include sample calculations for percent yield and provide sample spectra analysis. You must upload your proposal as a single document...
