results in a racemic mixture of benzoin. If both carbonyl groups are reduced‚ the product results in a meso-hydrobenzion or a racemic mixture of hydrobenzion. The goal of the experiment is for the student to reduce benzil and use melting point‚ TLC‚ and IR to determine the stereochemistry of the resulting product. Figure 2: Benzil reduction mechanism: Key experimental details‚ observations and results: The initial reaction solution including the 1.011g of benzil and 10ml of 95% ethanol appeared

The formation of the product was verified by performing a Bromine test as well as an analysis using IR Spectroscopy. A percent yield of 8.33% was obtained. Introduction: In an elimination reaction‚ two substituents are removed from a molecule in either a one or two-step mechanism. There is a removal of a leaving group and a proton to form alkenes

What constitute Tax crimes? A taxpayer committing an act “willfully.” In proving tax fraud the IRS looks for behaviors that determined the taxpayer’s willful intent‚ and conducts that may determine illegal tax evasion such as the existence of a tax deficiency and an affirmation of an attempted evasion.

An IR spectroscopy of the product was also performed. Results of the IR absorptions of this experiment were compared to the IR absorptions of standard functional groups as identified by the University of Puget Sound. Three main absorption bands were formed at 3373.46 cmˉˡ‚ 1635.71 cmˉˡ‚ and 1101.39 cmˉˡ. The absorption
