A Qualitative Analysis of Two Organic Unknowns: Structural Elucidation and Subsequent Compound Derivation via the Direct Observation of Chemical, Physical, and Spectroscopic Molecular Properties Introduction The characterization and classification of an unknown organic compound (or multiple compounds) is a frequently implemented lab testing the cumulative skills of undergraduate students or lab novices at various Universities and related institutions. Moreover, necessitating students to apply various techniques learned throughout the lab course exhibiting individually varying degrees of retention in us of […]
Investigating Substitution Reactions of Various Alcohol-Containing Compounds Kristen Powell, Morgan Sanders, Robert Walker Department of Chemistry and Chemical Biology, IUPUI, 402 N. Blackford St., Indianapolis, IN 46202 This is a Laboratory Journal of Organic Chemistry Note for synthesis reaction data obtained in the Organic Chemistry Laboratory—All information was experimentally conducted. This article should be used as a reference when conducting your own synthesis reactions. Three reactions containing alcohol groups, on primary and secondary carbons reacting with halide groups have been […]
By: Omish Samaroo Introduction The purpose of this lab is as follows: 1) to learn about coordination compounds through the synthesis and analysis of a potassium ferrioxalate hydrate salt and 2) to use the techniques developed in previous labs to determine the empirical formula of the ferrioxalate salt. The ferrioxalate salt has the empirical formula Kx[Fey(C2O4)z]•nH2O. The values of x, y, z, and n are ascertained through determining the percentages of K, Fe, C2O42-, and H2O; converting these percentages to […]
By: Ciaran Forde and Catherine Garbutt ABSTRACT: All projects must be accompanied by an abstract. The abstract should briefly state the problem or purpose of the research, indicate the theoretical or experimental plan used, summarize the principal findings, and point out the major conclusions. Abstract length is one paragraph. INTRODUCTION: RESULTS & DISCUSSION: After analysis of the chromatograms obtained in the separation of solutions AP and PC we decided that the 70% pH 3.5 buffer with 30% methanol gave the […]
By: David Gould Partners: Alaina Nunn, Stephanie Bolini CHEM 322L | February 17, 2014 – Quantum Dot Abstract: This experiment works to determine how quantum dots are prepared in a laboratory setting, and their analysis spectroscopically. With uses as semiconductors in the electronic industry, quantum dots perform faster due to their small size. Being so small these nanoparticles do not obey the laws of classical physics and must be studied in the quantum realm. Various quantum mechanical models are discussed and it […]
James Robertson Chemistry 2220 Determining the pKa of Bromothymol Blue by spectrophotometry Abstract To determine the pKa of an acid-base indicator, specifically bromothymol blue, different amounts of both 0.1M NaOH and 0.1 M HCl were added to a solution of fixed concentration of bromothymol blue and the pH was monitored via pH meter. At different pH readings around the researched pKa of Bromothymol blue we measured absorbance of the buffer solution. By superimposing the absorbance graphs, two wavelengths of absorbance […]
