SUMMARY
The discussion centers on the likelihood of vanillin formation based on infrared (IR) spectrum analysis. Participants argue that the IR spectrum indicates the presence of a strong C=O absorption peak at approximately 1740-1720 cm-1, which is significantly stronger in the product spectrum compared to the reagent spectrum of 2-methoxyphenol. This discrepancy contradicts the mark scheme's assertion that vanillin formation is unlikely, as the peaks in both spectra are similar, leading to confusion regarding the interpretation of the IR data.
