Table 1 organizes all observational and statistical data throughout the experimentation. Mass and volume amounts from various reagents were based upon these values and therefore are insignificant in a table. Each beginning, intermediate, and final product demonstrated shows the initial mass recorded before the next reactionary process began. At the end of each experimentation set, a dollop of sample was utilized to examine IR peaks and melting point range. The IR peaks displayed are the peaks present in the experimental samples that support the pure identity of the product. General observations during and after procedures were noted and are displayed above.

DISCUSSION

The first place to start on overall success of the experimentation would be the IR and melting point values. If the IR and melting point reveal to match exactly with literature values, the whole of experimentation can be deemed successful. Unfortunately, the reality is not as simple, for even a slight impure peak or skewness in melting point shows flaw in the sample product. Benzaldehyde was the first chemical in question. For this lab example, pure benzaldehyde was provided. For exemplary purposes, the IR of benzaldehyde was taken to track the peak alterations that could occur in later steps. The melting point provides further evidence of the purity of the benzaldehyde, but purity was assumed and therefore melting point was not taken. Benzaldehyde is a simple aromatic compound with a aldehyde group; therefore, expected peaks are the aromatic ring constituents, C=O bond representative of aldehydes, and C-H bonds representative of aldehydes. According to the expected literature values in place for this functional groups, benzaldehyde was sufficiently pure, containing all the correct values. With the correct IR spectrograph available, all following IR samplings follow stepwise in junction with the first. Further skewness can thus be considered flaw in procedure and not benzaldehyde. Benzoin condensed from a catalyzed reaction with Vitamin B and benzaldehyde, mixed with various basic and acidic
