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
