The previous lab that was conducted dealt with oxidation, which is referred to as a compound gaining oxygen or losing electrons (Wyman, 2015). This week’s lab consisted of a reaction that was the opposite of an oxidation and it is known as a reduction reaction. To be more specific a reduction reaction is when the reactant that is present gains electrons, which is response lowers the overall formal charge of the compound. For instance, if there are two hydrogen ions and each one has a positive charge of plus 1 the addition of two electrons will cause hydrogen gas to for, which is neutral. This is due to the fact that an electron has a charge of minus 1. According to one source reduction “often occurs when metals are reacted with acid” (Helmenstine,

This happened to be a clear oily substance on the bottom of the Erlenmeyer flask, which could easily go unnoticed. Another thing that is provided by the results is an IR spectrum, which when analyzed it revealed that the functional groups present in the final product, 2-methylcyclohexanol, was indeed produced. The way that is revealed is through the peaks that are present on the IR spectrum because each peak represents a different functional group based on the location of the peak and the strength of it. For 2-methylcyclohexanol, the main identifying functional group would be the OH, which would be represented by a broad peak at approximately 3300 cm-1, and this peak is present. Also the IR can indicate that the functional groups present in the starting material, 2-methylcyclohexanone, in no longer there in the final product. The main identifying peak to confirm this would be whether or not a peak is present around 1700 cm-1, which would indicate a carbonyl group. That peak is not present in the IR spectrum, meaning that the starting material is not present. As for percent yield it was 57%, meaning that of the total possible amount of product that could have been collected under ideal conditions only 57% of that was collected. Then there is the 1H NMR, helped determine the ratio of both the cis and trans form of 2-methylcyclohexanol. A process called integration, which uses the areas under the corresponding peaks, did this. The peak for trans is at approximately 3.1 ppm and cis is approximately 3.8 ppm. Both peaks under the corresponding peaks are practically the same, .99 for cis and 1.0 for trans, that means that the ratio is 1:1
