Anthracene and maleic anhydride

Take the time to validate and double check the source of the data. Anthracene was the diene and maleic anhydride was the dienophile. The percent yield of the crude product was 69.03%. Following recrystallization of the product using xylene and vacuum filtration, a percent yield of 37.42% for the recrystallized product was collected.

This was low due to the fact…show more content… Students Calculated an Rf value of 0.93 for Anthracene, an Rf value of 0.63 for Maleic Anhydride, and an Rf value of 0.78 for the crude product. These results show that Anthracene was the least polar solvent and Maleic Anhydride was the most polar.

First you need to find the molar mass:-look up on the periodic table what is called the atomic weight or molar mass (should be under the symbol). This is the number of grams in one mole of this element. -C: 12.01 g I'm wondering why maleic anhydride adds to the middle cycle of anthracene, and not the outer two.

All of the compounds used in this experiment are slightly toxic and should not be ingested.

The Diels-Alder lab uses two reagents: anthracene and maleic anhydride to make the product: 9,10-Dihydro-9,10-ethanoanthracene-11,12-Dicarboxylic Anhydride Assume you start with 1.012 gram anthracene and 0.505 grams maleic anhydride: what is the theoretical yield of the product? 1.012 grams Anthracene 1 mole Calculations: -Converting grams of Anthracene to moles-1.0 g Anthracene x 1 mole Anthracene 178.23 g Anthracene = 5.6 x 10 − 3 mol Anthracene-Calculating the mass of how much Maleic Anhydride to use:-5.6 x 10 − 3 mol Anthracene x 98.06 g Maleic Anhydride 1 mol Maleic Anhydride-= 0.549 g Maleic Anhydride-Since 1.0g of Anthracene and 0.55g of Maleic Anhydride was used, the theoretical yield can be calculated as: -0.55 gC 4 H 2 O 3 x 1 molC 4 H 2 O 3 98.06 gC 4 H 2 O 3 x 1 molC 18 H 12 O 3 Anthracene was the diene and maleic anhydride was the dienophile. The percent yield of the crude product was 69.03%.

While the product is not an insecticide and does not Figure 2. Reaction to form cis -Norbornene-5,6-endo -dicarboxylic anhydride (Pavia 417). (2) Write the potential Diels-Alder reactions of maleic anhydride and anthracene, and (3) estimate the reaction enthalpy changes for these and for the analogous Abstract. The first page of this article is displayed as the abstract. The influence of light on the Diels-Alder reaction between anthracene and maleic anhydride.

Anthracene was the diene and maleic anhydride was the dienophile. The percent yield of the crude product was 69.03%.
