Phenol with h2o
Webphenol is a benzene ring with a hydroxil -OH attached, it disolves in water acting ss an ácid: BzOH+H2O -> BzO(-) + H3O(+) the thing is that the phenoxide BzO(-) is very stable as it is able to delocate its negative charge. WebPhenol reacts with dilute nitric acid at room temperature to give a mixture of 2-nitrophenol and 4-nitrophenol. With concentrated nitric acid With concentrated nitric acid, more nitro groups substitute around the ring to give 2,4,6-trinitrophenol (old name: picric acid). Questions to test your understanding
