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

however‚ sometimes we actually remember a misrepresentation of what’s really occurred. This is known as the misinformation effect‚ where misleading information distorts our memory of the true event. Important in a variety of aspects‚ these memory errors become especially crucial in terms of courtrooms and eyewitness testimony. Interestingly‚ 75% of false convictions are due to an eyewitness identifying the wrong person or misreporting how an event actually occurred. Witnesses aren’t intentionally

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

Objective: One objective was to figure out if the burnt Mg ashes weigh more than the product which is Magnesium Metal. Another objective was determining the formula of the compound that results when Magnesium and Oxygen react. Theory: The purpose of this lab was to confirm the chemical formula of magnesium oxide by comparing the masses of pure magnesium solid prior to any reaction and magnesium oxide solid after a reaction between all of the magnesium and oxygen from the air when heated from

IP Proposal I. Title- Correction fluid from chalk II. Problem -how to make correction fluid from chalk dust safer? a.) Hypothesis - If this correction fluid won’t have any solvents/chemicals‚ then it won’t be harmful to the nose/body. b.) Objectives of the study -the objective is to create a safer correction fluid‚ to avoid it from being an inhalant. c.) Significance of the study -the significance of the study is to reduce the solvents and other chemicals that are harmful to the body when
