b. In nature, COT adopts a "tub-shape," as was shown in class. Assuming the molecule distorts to this non-planar geometry is COT aromatic, anti-aromatic, or non-aromatic? C. George Olah and coworkers reported a relative of COT shown above, 1,4- dimethylcyclooctatetraene dication. The 'H NMR shows a set of 3 signals with relative integrations of 2:1:3 at 9.96 (two overlapped peaks), 9.90, and 3.98 ppm chemical shift. Explain why the signals at 9.96 and 9.90 show such a low field chemical shift (hint: it is not alone sufficient to say this is due to the positive charge). Second hint: use the a MO diagram you created in part a. to help answer this.
please answer Question 2) ie. which of the following compound has lower Rf value? also please explain it.
help please answer in text form with proper working and explanation for each and every part and steps with concept and introduction no ai no copy paste remember answer must be in proper format with all working
Biginelli product to the left The actual Hd atoms in the Biginelli product have slightly different chemical and physical properties. As a result, they create two separate 1H-NMR signals and display a two-bond coupling (2 JHH). Identify the cause of these two Hd atoms having slightly different chemical and physical properties by making explicit reference to the Biginelli product. Biginelli product to the left.
