Why are aryl diazonium ions more stable than alkyl diazonium ions ?

Aryl diazonium salts are very good synthetic reagents that can be used for the preparation of a wide variety of organic compounds What is coupling reaction? Give one example.

Aniline is an aromatic primary amine.Starting from aniline a number of organic compounds can be prepared.How is the phenol obtained from benzene diazonium chloride?

Arene diazonium salts are more stable than alkanediazonium salts due to dispersal of the positive charge on the benzene ring. Obviously, electron-donating groups favour diazotisation by retarding the decomposition of diazonium salts to phenyl cation. The high reactivity of arenediazonium salts is due to the excellent leaving ability of the diazo group as N_2 gas. Consider the following ions: The reactivity of these ions towards azo coupling reactions under similar conditions is

Obviously, electron-donating groups favour diazotisation by retarding the decomposition of diazonium salts to phenyl cation. The high reactivity of arenediazonium salts is due to the excellent leaving ability of the diazo group as N_2 gas. Which of the following arylamines undergoes diazotisation most readily?

Carboxylic acids can be prepared using Grignard reagents. Why is benzoic acid more acidic than ethanoic acid?

How woụld you prepare 4 - methoxy phenol from bromobenzene in not more than 5 steps? State clearly the reagents used in each step and show the structures of the intermediate, compounds in your synthetic scheme?

How will you prepare the following compounds from benzene? You may use any inorganic reagent and any organic reagent having not more than one carbon atom, i. MethyI benzoate ii. m -Nitrobenzoic. acid iii. p-Nitrobenzoic' acid iv: Phenýlacetic acid v. p-Nitrobenzaldehydè.
