The Configuration Of Dichlorodiphenylethers, Wayne Lavelle Brantley

Honors Theses

No definite molecular configuration of diphenylethers has ever been substantiated by experimental proof. Due to the free rotation of the benzene rings about the oxygen linkage, the diphenylether can take any number of spatial configurations. Some theoretical work has been done in trying to determine the molecular structure, but it was felt that careful examination of the high resolution nuclear magnetic resonance spectra of the ethers would be useful in determining a structure.

Synthesis And Nitrosation Of 5,8-Dimethylhydrocarbostyril And Hydrocarbostyril, Harold Leigh Frye

Honors Theses

Research was undertaken this year to complete Huisgen's efforts by synthesizing the six-membered ring N-nitrosobenzo­lactam. This gap was left by Huisgen due to his unsuccessful attempt to produce N-nitroeohydrooarbostyril. My efforts were applied to this problem; namely, the synthesis of the six-membered N-nitrosolactam of hydrocarbostyr11 and 5,8-dimethylhydrocarboetyril.

Electrostatic Models Of Bonding In Molecules, John Joseph Moore Jr.

Honors Theses

Calculations of the energy differences between ground and excited states will be presented. A comparison of the results will be made.

Kinetics Of The Deformylation Of 2,6-Dichlorobenzaldehyde In Moderately Concentrated Sodium Hydroxide, Clifford William Coughlin

Honors Theses

Bunnett, Miles, and Nahabedian (3) studied the kinetics of the alkali cleavage of 2, 6-dichlorobenzaldehyde at base concentrations ranging from .211M. to 1.86M. They found that the simplest mechanism which gives an adequate account of the kinetics is represented by equations (I) and (II). For the step presented by equation (II), kc is the concentration independent second-order rate constant. The purpose of this project was to expand the region studied to the highest feasible base concentration.

Radiation Chemistry Of Aqueous Chloroform Solutions, Henry Douglas Kutz

Honors Theses

Saturated aqueous chloroform solutions have been irradiated with gamma rays from a cobalt-60 source. G values for the formation of HCl in oxygenated and deaerated solutions have been determined. Preliminary work involving the determination of hydrogen gas from the irradiated solutions is reported.

A Review Of (P→D) Π-Bonding In Silicon Compounds, Donald Robert Siebert

Honors Theses

In spite of all the work done since Brockway and Coop's articles appeared in 1938, the problem of the use of silicon's 3d-orbitals in bonding still remains inconclusive.

An Ultraviolet Absorption Study Of The Carbamate Reaction As An Explanation Of Carbon Dioxide Transport In The Blood, Bruce Raymond Cassidy

Honors Theses

This research project was undertaken in order to determine the applicability of ultraviolet absorption spectroscopy as a means of studying the carbamate reaction of carbon dioxide with glycine or diglycine. These compounds are thought to model the physiological substrate hemoglobin. Where for glycine R = -CH2- and for diglycine R = -CH2-CO-NH- CH2-. The reaction involves only the non-ionized alpha-amino group of the conjugate base species. It is therefore necessary that the reaction be run in a moderately basic medium, but at pHs not greater than ten. The ultraviolet absorption spectra for the conjugate acid, zwitter-ion, and conjugate base of …

Attempted Oxidation Of Benzaldehyde With Sodium Bismuthate (Part One). Reduction Of Xanthene By Lithium In Methylamine (Part Two), Gordon Lee Schiff

Honors Theses

The purpose of this investigation was to determine whether sodium bismuthate would oxidize an aldehyde containing only one oxygen atom. Benzaldehyde was selected for these studies because it is a relatively good reducing agent and is not likely to undergo condensation reactions. (Part One).

The primary objective of this research is to confirm Nielsen's proposal that (I) and/or (II) is the oxidation product of 1,2,3,4-tetrahydrofluorene. In doing so, this project is also concerned with the attempted reduction of xanthene and the subsequent oxidation of its reduction product. (Part Two).

Determination Of Calcium By The Coulometric Generation Of Oxalate Ion, Brian Jude David Koch

Honors Theses

The purpose of this research was to develop an electrode sensitive to calcium ion concentration that could be used to detect the endpoint in an automatic titration involving the generation of oxalate by the reduction of lead oxalate.
