The Preparation of Methyl Salicylate Introduction: Esters have various smells that differ due to the types of carboxylic acids and alcohols one mixes together. This is called esterfication. The reaction is catalyzed by an inorganic acid usually H2SO4 Purpose: In this lab Methanol alcohol and Salicylic acid were reacted together to form Methyl Salicylate. This was done to determine the characteristic odour of the Methyl Salicylate. Safety: Safety goggles must be worn at all times. Methanol: Toxic

Wars have been fought for thousands of years with different fighting styles and varying tactics. Fighting styles have been evolving since the dawn of time‚ as men have been learning how to defend themselves better and how to produce superior weapons. The weapons that were used in battle have become more deadly at an increasing rate. In World War I alone‚ more than 16 million people died‚ which made it one of the highest ranking wars in death total a war ever. Trench warfare was used extensively in

The mixture then turned a reddish‚ pink color with the addition of 9.1g benzophenone in 100mL anhydrous ethyl ether. During the reflux the reaction mixture first turned a “pepto bismal” pink color then became a thick white liquid/solid. When the sulfuric acid was added the solution turned a yellow

Abstract: The purpose of this lab is to prepare phenylmagnesium bromide‚ a Grignard reagent‚ and react it with benzophenone to give triphenylmethanol. Once made‚ the Grignard reagent will do a nucleophilic attack on the carbonyl carbon of the ketone‚ benzophenone. The result is an alkoxide that is then protonated to give the alcohol‚ triphenylmethanol. The purity of the final product will then be considered by melting point and IR spectroscopy. Final purified triphenylmethanol weighed 8.02 grams

These series of reactions synthesize the Schiff Base ligand and Nickel(II) complex of the Schiff base ligand. 0.36g of the Schiff base ligand is yielded and 0.1g of the nickel complex is yielded from the 0.36g Schiff base ligand and 0.5g nickel acetate.

Introduction: In this experiment‚ when vinyl strip and acetate strip is rubbed by tissue‚ it will charge the vinyl strip negatively and acetate strip positively caused by the transfer of electron between the strip and tissue. If molecules have non zero bond dipole‚ because polar molecule must have a non-zero molecular dipole where electron spend more of their time closer to one atomic nucleus than the other and make one end partially positive or negative than the other end. Different charge will
