Hint:To answer this question, you should recall the concept of diazonium salts. The diazonium salts refer to the class of organic compounds with a general formula where is an organic or inorganic anion and R is an alkyl or aryl group.
Complete step by step answer:
Diazonium salts two nitrogen atoms with one being charged. Some examples of these salts are Benzenediazonium chloride, benzene diazonium hydrogen sulfate, benzene diazonium fluoroborate etc. Diazonium salts are one of the most versatile combinations of organic and inorganic components.
Generally, diazonium salts have as X. The name of these salts is based on the presence of the group or the diazonium group.
The naming of these salts is done by adding the suffix diazonium to the parent hydrocarbon from which they are derived and then it is followed by the anion X such as bromide. The important properties of Diazonium Salts are:
-They are ionic.
-They are water-soluble.
-Aryl diazonium salts are colourless crystalline solids.
-Benzenediazonium chloride is soluble in water but reacts with it only when warmed.
-Benzenediazonium fluoroborate is not soluble in water. It is pretty stable at room temperature.
From the above properties, we can conclude that the correct answer to this question is option B.
Note:
You should know about the Importance of Diazonium Salts:
-Used in dye and pigment industries and are used to produce dyed fabrics.
-Used in document reproduction due to their property of breaking down near the ultraviolet light
-Diazonium salts can easily be used to produce cyanobenzene which otherwise cannot be produced using direct halogenation
-It is not possible to prepare substituted aromatic compounds by direct substitution in benzene. For these compounds, we use the replacement of the diazo group in diazonium salts.
