Triphenylmethyl Synthesis Lab Report

Abstract In this laboratory, methanol is reacted with a tertiary alkyl chloride to make ether. The triphenylmethyl is isolated from the triphenylmethyl chloride. Methanol is then added and the class does the recrystallization . The methanol acts as a solvent for the reaction as a nucleophile. Because it is a tertiary benzylic halide, the reaction is considered an SN1 type. To test the purity, the class then uses a TLC. When one places,” a spot of the substance on the absorbent surface of the TLC plate, the solvent (or solvents) run up through the absorbent,” (Zubrick223). The initial mass of the reactant, triphenylmethyl chloride was 2.006 grams. The experiment yield is 1.589g, which is a 80.3% yield. The triphenylmethyl methyl ether is almost pure with only a 0.05 difference in Rf values. Introduction The purpose of this experiment is to create an organic compound by a SN1 reaction. The starting material is triphenylmethyl chloride which reacts with methanol to produce an ether. Methanol is the solvent and nucleophile of the reaction. Since triphenylmethyl chloride is an alkyl halide, it is an electrophile. Methanol and…show more content…
On the other hand, the crude product versus the known product is similar which makes them identical. This also interprets to the products and reactants were pure. Then, the 2nd TLC plate was based on the interval of the student’s product while it was heating.. The TLC plate shows purity as well as the concentration gradually increasing. This is what prevents the spots from becoming darker during the 15 minute reflux process. The initial amount was 2.003 grams and the end product weighed 1.468 grams. The results show that the crude sample that was made from the lab had around the same purity with that of the known sample, thus, the experiment was
