At what position(s) will electrophilic aromatic substitution occur for the following compound: phenol? What aromatic product do you expect to obtain from the oxidation of the mentioned substance with KMnO4? What are aromatic hydrocarbons? Give a detailed description of the bonding in benzene. The ...
Ans. Phenol is a poor acid. In aqueous solutions within the pH range of 8-12, it is in equilibrium with the phenolate anion C6H5O- (also phenoxide). Phenol is more acidic than aliphatic compounds as it contains an OH group. The phenoxide anion is stabilized by the aromatic ring resona...
What is an aromatic compound? Aromatic Compounds: Aromatic Compounds follow the Hackle's rule according to which a ring is aromatic if it has the property called planarity, delocalization of theπelectrons in the ring and there should be(4n+2)π(where n is a whole number) electrons present ...

10). Polyphenol dominance was defined at the genus level as contributing an average of at least 10% of polymer, monomer or phenol active expression in a habitat (per depth). This was chosen as 10% corresponded to a P value of 0.05 in the overall distribution (Supplementary Fig. 10). ...
