The theoretical yield and melting point of the compound is determined. by vacuum filtration and wash with small amount of ice-cold water r and dissolve approximately 5.0g of the solid acetanilide product in 30 mL of glacial acetic 8. 22333. STAGE1 . Theoretical Yield: 93 g of aniline gives 135 g of acetanilide. This method resulted in a 96% yield of 4-bromoacetanilide… Weigh out ~280 mg of acetanilide in a 10 mL r.b. University of Wisconsin-Madison, Madison, WI 53706.
5. 00 Bromine soln. Calculate the percent yield of acetanilide if you started with 2.0 mL of aniline and 2.0 mL of acetic anhydride and obtained only 1.5 g of acetanilide. Find the melting point of the product, then obtain the 1H NMR of the product in CDCl3. 0912g/0.
This. The molar mass of acetanilide is 135. 0 Glacial Acetic acid60. 2 g/mol Given 8.2 g aniline is 8.2/93.1= 0.0881 moles , this will need 0.0881 moles of acetic anhydride to form 0.0881 mole acetanilide The answer is … Dry the solid and obtain the mass. Procedure/Observations: 1.

Show detailed work clearly indicating the limiting reagent, theoretical yield, etc. Percentage yield = Mechanistic equation for each step in the preparation of p-bromoaniline from aniline. DOI: 10.1021/ed073p267. 4.
acetanilide occurs at the para position. Educ., 1996, 73 (3), p 267. iosrjournals. Results Calculation of Theoretical Yield: Mass of acetanilide taken, m1 = 100mg = 0.1g Molar mass of acetanilide, M1 = 135.163 g/mol → No. Molecular formal of acetanilide = C 8 H 9 NO. Paul F. Schatz.
Using the actual mass and the theoretical yield, the percent yield was calculated and the product was handed in. X = (135 × 5.15)/93 = 7.48 g. Theoretical yield = 7.48 g. Practical yield = _____ g Then, add 2.0 mL of glacial acetic acid using a …
Therefore, 5.15 g of aniline will give? The objective of this experiment was to use melting point and NMR to determine which of two isomers, ortho or para, would most likely form after brominating Acetanilide through electrophilic aromatic substitution. Reaction: Bromination of Acetanilide Mass of reactant(acetanilide) = 0.5380g Mass of product = 0.1148g Ratio reactant-product = 1-1 Theoretical yield calculation: 1) Determination of limiting reactant and theoretical yield: a. 9. The course includes the following experiments: esterification …
