  • - 6-Diphenyl-2-Cyclohexenone Lab Report

    In the IR spectrum, RM-10-1i, peaks that are present correspond to the functional groups in 6-ethoxycarbonyl-3,5-diphenyl-2-cyclohexenone. These functional groups are sp2 hybridized carbons at 3031 cm-1, sp3 hybridized carbons at 2981 cm-1, a carbonyl at 1735 cm-1, aromatic carbon-carbon stretching at 1660 cm-1, an ester carbon-oxygen stretching at 1144 cm-1, and alkene carbon-hydrogen stretching at 698 cm-1. There was no alcohol present in this spectra, indication that all of the catalyst was removed successfully. Also the presence of alkene functional group indicates neither starting material was present in the final product. This spectrum also resembles the spectrum in the procedure handout indicating the known wavelengths for this product. With the functional groups present, and also the matching spectra, the identity of the product is…

  • Body Synthesis Protocol Analysis

    The banana-yellow coloured solution was stirred for 30 minutes, then 1 (6.00 g, 1 equiv, 45.4 mmol) was slowly added over 30 minutes, resulting in a milky brown solution colour. The solution was stirred for a further 18 hours following which two aliquots of hexanes (100ml) were added. The solution was filtered through a pad of silica, and then concentrated in vacuo and the product was purified by column chromatography (10% ethyl acetate in hexanes) to give a colourless oil (1.21 g, 9.30 mmol)…

  • Ethyl Cinnamate Synthesis

    Experiment 5 Synthesis and NMR Spectroscopy of ethyl cinnamate Introduction: Wittig reactions involve the stereoselective synthesis of olefins from phosphonium ylides and aldehydes or ketones, where the carbonyl bond is converted to an alkene double bond.1 The variety of suitable reagents and the relatively mild experimental conditions facilitate their industrial applications, such as the synthesis of epoxides, esters, carotenoids and vitamin A.2,3 Specifically, the ester ethyl cinnamate is used…

  • Nucleobases Lab Report

    Interactions of Nucleobases: NMR Investigations by H. Sapper and W. Lohmann Introduction Nuclear magnetic resonance (NMR) spectroscopy is often a very useful tool to identify organic molecules based on the atomic nuclei interactions with their environment. Recent advances have made use of the technology in protein, nucleic acid, and complex natural products structure identification. [1, 2, 3] Its origins lie in the works of Felix Bloch and Edward Purcell, who used the discoveries of Isidor…

  • Ferrocene Lab Report

    Objective The purpose of the experiment is to synthesize a compound with an organometallic iron-carbon bond and use infrared spectroscopy to investigate the unconventional sandwich structure. In addition, the experiment aims to understand pi-bonding of an arene ring, use cyclic voltammetry to understand the redox capacity of ferrocene, and explore the barriers between formal inorganic and organic chemistry definitions. Introduction Ferrocene was discovered unintentionally in 1949 when…

  • Argumentative Essay: Is Apollo 13 A Failure?

    “Houston, we have a problem.” said Jim Lovell, an astronaut of Apollo 13, when the oxygen tank explored in the Space in 1970. After the talk, this lunar exploration gained a worldwide concern. Three astronauts in the craft fought with numerous disastrous faults and eventually back to the earth. In 1995, this regrettable story was even recorded as a historical docudrama named Apollo 13. Such social repercussion brought up a perspective that Apollo 13, one of the most well-known explorations of…

  • Apollo 13 Analysis

    the movie Apollo 13. More importantly, the concepts that stuck out to me during the whole movie were a successful failure, making mid-course corrections, teamwork, prioritizing, communicating and lastly assessing and planning for risk. At first I wasn’t sure that the movie was a “successful failure” but towards the end of the movie it was said that it was such. There was a failure of never reaching the moon, yet it was a success with teamwork both on and off the ship. I would have never thought…
