In organic chemistry, a diethynylbenzene dianion is an anion consisting of two ethynyl anions as substituents on a benzene ring. With the chemical formula C6H4C2−4, three positional isomers are possible, differing in the relative positions of the two substituents around the ring: * ortho-diethynylbenzene dianion * meta-diethynylbenzene dianion * para-diethynylbenzene dianion The gaseous state of all three anions are of theoretical interest. They have been generated by decarboxylation of benzene dipropynoic acids, using the technique of mass spectrometry. The three isomers of the dianion are the three strongest known superbases ever, with the ortho isomer being the strongest, with a proton affinity of 1,843.987 kJ/mol (440.723 kcal/mol). The meta isomer is the second-strongest, and the para isomer is the third-strongest. (Wikipedia).
Acetaminophen/Paracetamol (Tylenol)
Acetaminophen, more commonly known by brand names such as Tylenol, is not a true NSAID, as it does not have anti-inflammatory properties. However, it is commonly discussed alongside NSAIDs as it has similar antipyretic and analgesic properties. Although its mechanism of action is not well-

Aspirin to Acetaminophen - Part 6 of 6: Acetaminophen from p-aminophenol
This is the final part of the series, where the p-aminophenol is converted to the acetaminophen. Using acetic anhydride, the p-aminophenol is going to be acetylated. The reaction is carried out in water at room temperature. Acetic anhydride does react with water, but it happens slowly.

The Cannizzaro reaction is pretty old, over 150 years old in fact, but it is still an important reaction in organic chemistry. It involves the disproportionation of two equivalents of an aldehyde, meaning one is oxidized to the carboxylic acid and the other is reduced to the alcohol. What
