Aniline to chlorobenzene

Conversion of Aniline to Chlorobenzene:- Step 1: Formation of Diazonium salt When the Aniline is tested with Sodium nitride and Hydrochloric acid, at a temperature between ( 0 - 4 ) ° C produces Diazonium salt of Benzene Step 2: Formation of Chlorobenzene This diazonium salt formed then is reacted with Cu 2 Cl 2 and Hydrochloric acid to undergo Sandmeyer reaction and produce Chlorobenzene: This conversion of Aniline to Chlorobenzene is a 2 step reaction.

Hint: We can prepare chlorobenzene from aniline by using Sandmeyer reaction, by using fittig reaction we can prepare diphenyl from chlorobenzene. Complete step by step answer: Sandmeyer reaction: “The Sandmeyer reaction is a chemical reaction used to synthesize aryl halides from aryl diazonium salts using copper salts as reagents or catalysts. It is an example of a radical-nucleophilic aromatic substitution”. It is a two-step reaction In the first step aniline is going to convert to benzene diazonium chloride using sodium Nitrate and aqueous hydrochloric acid. Fittig reaction: “Fittig reaction is the chemical reaction of aryl halides with sodium metal in the presence of dry ether to give substituted aromatic compounds”. Two moles of chlorobenzene react in presence of sodium and dry ether and forms biphenyl compounds and 2 moles of sodium chloride (insoluble in dry ether).

Answer: There are two phases in the conversion of aniline to chlorobenzene which are as follows: – The reaction of aniline with NaNO 2 /HCl is the initial stage. The consequence is the creation of benzene diazonium chloride, a diazonium salt. This reaction takes place between the temperatures of 0 ° C and 5 ° C . The diazonium salt is then treated with CuCl in the next step. The Sandmeyer reaction is the common name for this process. A radical nucleophilic aromatic substitution is an example of this reaction. • What is the formula for a3+b3? • In Indian rupees, 1 trillion is equal to how many crores? • Name the smallest and the largest cell in the human body • Examples of herbs, shrubs, climbers, creepers • How do we convert 1 g/cm3 to kg/m3 • What is the molecular mass of glucose molecules (C6H12O6) • Find five rational numbers between 2/3 and 4/5 • How many zeros are there in 1 lakh?
