EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol

Experiment 2: IDENTIFICATION OF UNKNOWNS BY TLC AND MP IN COMBINATION Introduction: Thin layer chromatography (TLC) is one of the most valuable techniques in organic chemistry. This is a best method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different

FIRE RESISTANT BALLOON: Materials - 1 matchbox - 1 candle - 1 yellow colored balloon - 1 blue colored balloon - Half a cup of water Procedure: 1. For this experiment‚ the independent variable is whether the balloon is filled with water or not. The dependent variable is what happens to the balloon when it is placed above the lit candle. This is determined by observing the balloon. The constants (control variables) are how much the balloon is inflated and the amount

process of distillation. Distillation is the separation of volatile substances mixed with nonvolatile substances by boiling the mixture to alter the phase of the volatile substance. The researchers used the simple distillation set up to conduct the experiment. 25 ml of The Bar Vodka was used and 7 ml of distillate was collected before a temperature of 95 degrees Celsius was reached. Collected distillate was then subjected to a flammability test to confirm ethanol content. The percent ethanol was computed

1. The Tuskegee study‚ as it came to be called‚ did not start out to be either deadly or a deception. State how the project actually began‚ and describe the events that led to its becoming a “deadly deception.” Initially‚ The Tuskegee study began when researchers noted a high prevalence of syphilis in the south‚ with an “epidemic” rated noted in Macon county. The documentary notes that there was mounting public health concern for the African American population because “germs know no color lines”

Austin Vandermey GS-1140 April 4th‚ 2015 Experiment We as a society have one big problem on our hands. This problem is sleep deprivation because there are not enough hours in the day to get stuff done. Between work‚ school‚ family‚ and leisure it seems like we do not have enough time to get are daily tasks done let alone have time for sleep. It is recommended by the U.S Department of Health that people need a solid eight hours of sleep to maintain good health. I don’t know about you

Experiment #1: Introduction to Experimentation Submitted by: Neann Klara M. De Jesus BS Psychology II Submitted to: Dr. Geraldine E. Tria ABSTRACT SUMMARY The first experiment done by the class was called “Introduction to Experimentation”. Its main objective is to give basic knowledge about some of the logic of experimentation. The class was divided into groups of 2. In each group there was an experimenter (E) and a subject (S). The experimenter instructed

In my community‚ I mainly volunteer at “I am my Brother’s Keeper” (IAMBK) and Southern Christian Leadership Foundation” on a daily basis. IAMBK is an after-school program targeted to low-income and single parent’s families in Tuskegee‚ Alabama.
