Answer 1

What are Diazonium Salts?

The diazonium salts or diazonium compounds are the class of organic compounds with general formula R−N2+X−. Here, X is an organic or inorganic anion (for example, Cl–, Br–, BF4–, 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 implies that it is cationic in nature.

Hence, they have two nitrogen atoms with one being charged. Benzenediazonium chloride (C6H5N2+Cl–), benzene diazonium hydrogen sulfate (C6H5N2+HSO4–), etc. are some of the examples of the diazonium salt.

Now, we look at the properties of diazonium salts. You can learn them as they are important from the exam point of view.

Answer 2

Answer:

The reaction of aniline with nitrous acid results in the formation of the diazonium salt this salt is the benzene diazonium chloride therefore, it is Generally prepared during the reaction itself by reacting NaNO2 with a mineral acid
