Chris CXXXX Organic Chemistry Lab Dr. Lyn XXXX 2 February 2012 Esterification of Isopentyl Alcohol to Isopentyl Acetate Procedure The technique for esterification that was employed in the experiment was to use a reflux apparatus (Figure 1) while heating in order to evaporate out water to drive our reaction into the product favored direction. The starting material of isopentyl alcohol (1.0 mL) and excess glacial acetic acid(1.5 mL‚ 17.6M) were eppendorf pipetted into a 5 mL conical vile. This

Materials and Methods In the experiment‚ a frog was obtained and dissected in a way to expose its heart and then tested using Lab Tutor software‚ a force transducer‚ and the PowerLab hardware (ADInstruments 2014). Frog dissection: Frogs that had been killed by being double-pithed were dissected as described in Lab Tutor. The frog was pinned down with the ventral side up. A longitudinal and a lateral incision were made along the frog’s abdomen. The skin was peeled back and the tissue and sternum

In fact‚ many people are pushed into this status due to many different reasons‚ such as gentrification or just difficulty finding a job. Walking down the Market Street of San Francisco‚ a bustling

rhetorical analysis‚ and synthesis‚ instructed by Dr. Tina Giovanielli. Although I believe all four arguments were strong‚ for the purpose of this reflective assignment I am going to choose one argument that I think is my strongest piece of writing then analyze it and explain why I think that is my best work. I believe my last assignment (synthesis) was very challenging at first but it ended up to be my strongest piece in the whole semester. Since I have never done any synthesis before this one‚ I found

The acetic acid mixed with acetaminophen created an impure sample‚ which was purified through the addition of a water/methanol solution. The percent recovery of acetaminophen from the impure sample to the pure

The Grignard Synthesis of Triphenylmethanol Abstract: Grignard synthesis of triphenylmethanol was achieved by use of the Grignard reagent phenyl magesium brominde. The organometallic grignard reagent was synthesized by use of a reflux apparatus recrystallization techniques. Once synthesized it was used in a Grignard reaction that involved nucleophilic addition to a carbonyl in order to make triphenylmethanol. The final product was solidified and recrystallized and spectral data was
