0.22g (percent yield of 86.9%). The percent yield after recrystallization‚ was 80.9%. INTRODUCTION The goal of this experiment was the synthesis of 3-nitrochalcone from 3-nitrobenzaldehyde and acetophenone as shown in Figure 1: Figure 1: Synthesis of 3-Nitrochalcone from 3-Nitrobenzaldehyde and Acetophenone Source: cnx.org The mechanism for the synthesis of 3-nitrochalcone is presented in Figure 2. The alpha carbon on the acetophenone is deprotonated‚ followed by the attack of the alpha carbon

Synthesis of 1-bromobutane from 1-Butanol using the SN2 Reaction Abstract: The objective of this experiment is designed to study the synthesis of 1-bromobutane from 1 butanol using a SN2 reaction.. The product will then be analyzed using a flamed loop test by use of fire. Reaction Mechanism: CH3CH2CH2CH2—OH H+ CH3CH2CH2CH2— +OH2 Br- CH3CH2CH2CH2—Br + H2O 1-butanol

Experiment 1: Synthesis of Copper Compounds Introduction This experiment involves the synthesis of compounds originating from pure solid copper. By applying solubility rules and the reactive properties of substances‚ many compounds which would otherwise be costly to extract from nature are able to be synthesized in the laboratory. Laboratory synthesized may sometimes be more economical than natural extraction‚ however it poses its own problems with the amount of substance that is actually yielded

Introduction In this lab‚ caproic acid was synthesized in a multi-step process that involved the synthesis of three intermediates – diethyl n-butylmalonate‚ potassium n-butylmalonate‚ and n-butyl malonic acid respectively. An IR was used to characterize the starting material‚ n-bromobutane‚ and the first intermediate‚ diethyl n-butylmalonate; while IR and NMR were used to characterize the final product‚ caproic acid. Reactions‚ Mechanism and Theory Caproic acid a.k.a n-hexanoic acid is a carboxylic

Experiment 13: Synthesis of 1-Bromobutane An SN2 Reaction Experiment #13: Synthesis of 1-Bromobutane an SN2 Reaction Introduction: In order to synthesize 1-Bromobutane an alkyl halide must be present to undergo a nucleophilic substitution reaction of an alcohol. Since 1-butanol is a primary substrate it will undergo an SN2 reaction with sodium bromide in order to convert the alcohol group to water which is a better leaving group and will in the end produce 1-bromobutane. Experimentally

Abdulfatah Momen R/W class One of the basic components of the community is children. Some of families think that having children bring problems to their life. Some of these families decide to work off children by medical science before children come to the life. The way that they choosing is abortion. Abortion was made by women who are pregnant‚ and they don’t want to have children. Abortion is the termination of a pregnancy by the removal of the fetus. Rates of abortion increase to be very

The people of America live in a country whose citizens are gifted with the system of Democracy where each person has their voice represented in decisions of the nation. The inherent responsibility of each voting age citizen of America is to research the positions and views of all candidates that represent them and then punch‚ mark‚ or press the space next to the candidate that they believe would best represent him or her. But not all Americans would care to look closely at the opinions of the election

In part A‚ solutions needed in the experiment were prepared‚ and the LabQuest was set up. By adding 100mL 6M HCl to 200mL deionized water‚ 300mL of 2M HCl solution was prepared. Then 150mL 2M NaOH solution was prepared by adding 100mL 3M NaOH to 50mL deionized water. Finally‚ the LabQuest was connected to the temperature probe‚ and set up to collect data every 15 seconds‚ the duration was set to be 180 seconds. In part B‚ three reactions were performed. In reaction 1‚ two Styrofoam cups were stacked
