WebbNitration is used to add nitrogen to a benzene ring, which can be used further in substitution reactions. The nitro group acts as a ring deactivator. Having nitrogen present in a ring is very useful because it can be used as a directing group as well as a masked … WebbNitration. Nitration is the process of adding a nitro group into an organic compound like aromatic compound, alcohol, glycol, glycerine, aromatic amine, and paraffin. Most …

WebbAromatic Nitration Reactions Nitration reaction involves the replacement of a hydrogen with a nitro (NO 2) group.

WebbBecause the benzene acts as a nucleophile in electrophilic aromatic substitution, substituents that make the benzene more electron-rich can accelerate the reaction. ... Phenol, C 6 H 5 OH, undergoes nitration a thousand times faster than benzene does. Nitrobenzene, C 6 H 5 NO 2, undergoes the reaction millions of times more slowly. WebbAromatic hydrocarbon – nitration. Nitration is a type of substitution reaction of aromatic hydrocarbon. In these reactions, one or more hydrogen atoms in the benzene ring get …

WebbNitration of toluene in the aromatic hydrocarbon molecule is carried out with a nitrating mixture (sulfuric and nitric acids). Catalytic properties are shown by sulfuric acid, which acts as a water-absorbing agent in this process. The equation of the process Nitration of toluene involves replacing one hydrogen atom with a nitro group.
