Yield curve

Before the start of this experiment, the theoretical yield was calculated. Based off the data, it was found that the limiting reagent is 3-nitrobenzaldehyde. The theoretical yield is determined by relating the moles of the limiting reagent to the moles of the anticipated product by a ratio obtained from the overall equation. The theoretical yield was calculated to be 1.3 g. However, the actual yield obtained was greater than the theoretical yield; in other words, the actual mass of the product was

Lidocaine (3) was prepared by nucleophilic substitution of α-chloro-2,6-dimethylacetanilide with 2(CH2H5)2NH (Scheme 3). Scheme 3. Synthesis of Lidocaine The yield of lidocaine was 17.3%. While the experimental yield was bad, a percent yield closer to 40-50% would have been a more realistic percent yield. Given the results, a significant amount of the product was lost during the reaction; likely, this occurred during transferring of mixtures between flasks. A portion of the product was

formula. When finding the empirical formula it is important to know how to find things such as the limiting reagent, percent yield along with the theoretical yield. The limiting reagent is a substance that will not let the reaction proceed because of its presence. The percent yield and the theoretical yield are both found by comparing the reaction and the experimental yield and recording those results. Introduction When it comes to chemistry, compounds will always more than one elements. These elements

properties were observed. It acted like a liquid when left alone, but it cracked when squeezed. In conclusion, the three experiments demonstrated the polymer’s wide spectrum of properties and a variety of its subgroups. As seen in Figure 3, the percent yield exceeded one-hundred, indicating a source of error. When weighing, the methyl acrylate

Abstract: The purpose of this lab is broken into two parts. The first is to identify the unknown compound by identifying its physical and chemical properties. Using various tests, the collected can be used to compare compounds to the UWC. The second part of identifying the compound is synthesizing the compound and then testing the created compound. The information gathered from days one and two were used to compare and verify the results. Introduction: Given the unknown compound, the goal was

no potassium nitrate was present the percent yield would be closer to 100% yield, but this is not the case. The percent yield for the evaporation collection was 144% yield which is not close to 100% yield. The evaporation collection procedure was able to achieve over 75% yield with a percent yield of 144%, while the vacuum filtration was unable to achieve the goal with only 56.9% yield. The evaporation collection was able to achieve the 144% yield by carefully transferring all of the liquid from

Calculation of Product Distribution of 2-Bromopentane and 3-Bromopentane Amount of Product:.631g 2-Bromopentane(Hydrogen G) Integration:.78 3-Bromopentane(Hydrogen F)Integration:.28 Mole Ratio of 2-Bromopentane to 3-Bromopentane: .78/.28=2.79 which is ~3:1 ratio .75 x .631= .47g 2-Bromopentane .25 x .631= .16g 3-Bromopentane This shows that 2-Bromopentane is the major product.

Part A- Aldol Condensation of Tetraphenylcyclopentadienone • After completing the experiment, a yield of 0.01 g of an impure, solid purple, precipitate was created, however this yield will not be considered for percent yield or for future use due to its impurity in nature. This conclusion on the purity of the substance is drawn from the information for pure tetraphenylcyclopentadienone; pure tetraphenylcyclopentadienone has a characteristic black/purple tint to its crystals, and said crystals are

The objective of this procedure is to produce a sample of p-acetamidobenzoic acid from the oxidation of p-acetotoluidide with potassium permanganate. Procedure Part A- Preparation of p-Acetamidobenzoic Acid • In a 250 mL Erlenmeyer Flask, 5 g (0.02 mol) of magnesium sulfate crystals were mixed with 1.9 g (0.013 mol) of p-acetotoluidide in 125 mL of de-ionized water. The resulting solution was placed on a hot plate and was steadily boiled until the solution reached 85°C, or until the solution reached
