EXPERIMENT 8 BOILING POINT n-Butyl Alcohol n-Butyl Alcohol‚ a four carbon straight chain alcohol‚ is a volatile‚ clear liquid with a strong alcoholic odor; miscible with water. It is flammable strongly with a luminous flame. Formula: C4H9OH Boiling point: 118 ºC Melting point: -89 ºC Tert-Butyl Alcohol Tert-Butyl Alcohol or “2-methyl-2-propanol” is the simplest tertiary alcohol. It is one of the four isomers of butanol. Tert-Butanol is a clear liquid (or a colorless solid‚ depending on

3 Questions I have: ● According to Asimov‚ when do people solve problems or make discoveries‚ and why? ● How does Asimov include the scientific information of Archimedes’ and Kekule’s discoveries necessary to help understand them better? ● What was Asimov’s idea behind “Eureka! Eureka!” and how did it fit into the purpose of the story? In the story The Eureka Phenomenon by Isaac Asimov‚ Asimov includes the scientific information of Archimedes’ and Kekule’s discoveries to help the audience und

EXPERIMENT 4: Synthesis of Salicylic Acid from Wintergreen Oil Abstract: The purpose of this experiment is to take methyl salicylate (wintergreen oil) and by heating it under reflux with NaOH as a solvent‚ and then cooling the mixture with H2SO4 as another solvent‚ synthesize salicylic acid. The final step involves purify the product to produce as pure a sample of salicylic acid as possible. This process allowed for the successful production of 1.406g salicylic acid‚ an 82.70% yield.
