WebbThe nitric acid is protonated by the stronger sulphuric acid, forming an electrophilic nitronium ion and water. This nitronium ion then acts as the electrophile in the nitration, forming a bond with the π electrons of the aromatic ring. Sulphuric acid is also a solvent for the workup, deprotonating the intermediate, which allows it to reform ... WebbInorganic nitrates and nitrites are generally more water soluble than organic nitrates and nitrates. Inorganic nitrates and nitrites are produced endogenously and exogenously. Organic nitrates and nitrites are mostly synthesized medicinal products.
