The goals of this experiment are to determine if the products derived from amide synthesis and Williamson Ether Synthesis are identical‚ and if one of the synthetic routes is more advantageous than the other. In Part 1‚ an attempt to synthesize acteophenetidin crystals by amide synthesis was made. We began by removing the colored impurities from the p-Phenetidine (reddish-brown) by placing 2g of the sample in 38 mL of hydrochloric acid and heating the solution to boiling point. Upon reaching just

Does Aspirin Effect Plant Growth Plant Science The question of this science fair project question is “Does Aspirin Effect Plant Growth.” This is a good question because aspirin help human get better but‚ will it help plant grow bigger. Or maybe it makes the plant grow faster? Or maybe it can make the plant not grow at all. In this science experiment I am using dieffenbachia plants. Dieffenbachia plants are usually house plants. This is great because this science experiment is being done in the
