Question

H cyclopentadiene maleic anhydride endo product exo product is not formed monia Tove rapid at 170 YC slow at 0°C oma ve H20, heat 4CO2H mp = 32 YC bp = 170 YC CO2H

How would I calculate the theoretical yield of endo-cis-norbornene-5,6-endo-dicarboxylic anhydride and endo-cis-norbornene-5,6-dicarboxylic acid? Can you please show me step by step? Can you show me the balanced chemical equation (with molecular formulas, not the pictures) with the mole ratios as well? How do we figure out the limiting reagent? Can you also show how to convert mL to grams for cyclopentadiene, if needed?

We used:

2g of maleic acid

6mL of ethyl acetate

6mL of ligroin (hexanes)

2mL of cyclopentadiene

Answer 1

molao mass of maleic acid = 116.1 g/mol moeic anhydride - 98.06 g/mol i mole of maleic acid = 116.1 g Imol 2 g of maleic acid = (2x1 ) mole of Mweis 1161 1 = 0.0172 mole il mole of maleic acid gives mole of moveis anhydode : 0.0172 mole maleic acid gives 0.0172 mole of anny donde 0.019, mole anhydodde = 0.0172 x 98.00 = 1.689 g moeic anhydroid Density of cyclopentadiene = 0.786 g/mol .::D= massi m ass = 0.786 X 2 M L = 1.572 g vo). i mole of cyclopentadiene = 66.1 g : 1.572 g cyclopendien e = / -572 )= 0.0 2378 mole Accooding to ed Imole of Cyclopentadiene deacts coith Imole of maleic anhydride is 0.0172 maleic anhydoide must reads coith 0.0172 Cyclopentadiene But beoe 0.02378 mole of cyclopentadiene is used. It means cyclopentadiene is excess and maleic anhydride is a limiting reagent:

I mole of maleic anhydride gives i mole of endo anny doide in 0.0172 mole of mweic anhydoide gives 0.0172 mole of endo anhydride is 0.0172 mole of endo anhydride = 164.16 X 0.0172 g = 2.823 g Theoretica yield of endo anby doide - 2.8239 ly, 0.0172 mole of endo anhydride gives 0.0172 mole of endo dicooboxylic acid. :: 0.0172 mole of endo dicaoboxylic acid = 182.16 *0.0172 = 3.1338 Theoretical yield of endo dicarboxylic = 3.133 g Equanion : C4H404 C5 H6 + C4H203 → Cg H1803 endo anhydride 1 Hao, beat Cg Hj004 endo dicarboxylic acid.
