Purpose, the object of this experiment was to reduce the ketone group of a cycloalkane into an alcohol group.
Ketone (reactant IR) 1720, alcohol (product IR) 3400, carbon Fingerprints 1500-600, table C: IR Spectrum Anomalies, gas chromatography further confirmed the purity of the product, showing the two expected isomers.To learn more, view our.IR spectrum and gas chromatography were conducted with the product.By using our site, you agree to our collection of information through the use of cookies.Nicht relevant, anstößig, nicht jugendfrei, sexueller Missbrauch von Kindern, feedback).The layer was removed and then two successive methylene chloride (2mL each) additions were used to extract the remaining product (in the bottom layer).Water (4mL) was added, allowing the product to separate as a mostly clear upper layer.This reduction reaction yields two possible isomers and the experiment intended to determine (via gas chromatography) whether the thermodynamic or kinetic product was more favorable (see Figure 1 below).Do you have lab reports like this on your computer?The hydroxyl group is more sterically encumbering than the methyl group and is more stable in the equatorial position.
