WebThe diazonium salts or diazonium compounds are the class of organic compounds with general formula R−N 2+ X −. Here, X is an organic or inorganic anion (for example, Cl –, Br –, BF 4–, etc.) and R is an alkyl or aryl group. The term is derived from two words. ‘ di’ refers to ‘two’, azo is indicative of ‘ nitrogen ’ and ium ... WebJan 21, 2024 · Answer: Diazonium salts are crystalline compounds that are colourless but darken when exposed to air. When heated or hit when dry, several diazonium salts of nitrates and perchlorates explode. As a result, these salts are not separated and are used in other synthetic preparations as soon as they are produced in situ. mpa単位とは
