Aniline can be produced from benzamide by the Hoffmann bromamide reaction. This process allows us to produce aniline from benzamide. When heating with a mixture of Br2 in the presence of NaOH or KOH (i.e. NaOBr or KOBr), the Hofmann bromamide reaction transforms primary amide into primary amine with one fewer carbon atom than the original amide. This process is called the Hofmann bromamide reaction.
The compound aniline is produced through the reaction of benzamide with sodium hydroxide and bromine.
Explanation: An aniline is produced from benzamide by treating it with bromine and aqueous sodium hydroxide. This results in the formation of an aniline that has one fewer carbon atom than the original amide. The following describes the reaction that takes place: This reaction is referred to by its formal name, the Hofmann bromamide/degradation reaction.
What kind of rearrangement is carried out in order to produce aniline starting from benzamide?
The organic process known as the Hofmann rearrangement, also known as the Hofmann degradation, involves the conversion of a primary amide into a primary amine that has one fewer carbon atom.
The reduction of nitrobenzene to aniline entails what steps.
Nitrobenzene is converted to aniline with the use of stannous chloride and strong hydrochloric acid. Other elements such as Zn or Fe may be utilized in its place of tin… After that, aqueous sodium hydroxide is added to the aniline salt in order to liberate the aniline. This process is known as the nitrobenzene reduction reaction.

The conversion from aniline to bromobenzene will take what form?
When aniline is treated with nitrous acid or sodium nitrite and hydrochloric acid at chilled temperatures, it gets converted to a diazonium salt called benzene diazonium chloride. This diazonium salt then either goes through Sandmeyer’s reaction, in which treatment with CuBr results in bromobenzene, or it can go through Gatterman’s reaction, in which the diazonium salt is…
How does one go about converting aniline into fluorobenzene?
An indication is that aniline can be transformed into fluorobenzene by first converting aniline to benzene diazonium chloride and then converting fluorobenzene from the benzene diazonium chloride. The end result of the reaction will be the incorporation of a fluorine atom in place of the amine group that was previously present in the benzene ring.
What are the steps involved in converting aniline to benzonitrile?
Ans: Conversion of Aniline to Benzonitrile: At lower temperatures, the reaction of aniline with sodium nitrite and hydrochloric acid results in the formation of benzene diazoniumchloride. Benzo nitrile is the product of this Benzene diazonium choride’s subsequent reaction with CuCN.
What happens when cold nitrous acid comes into contact with aniline?
(b) Aniline: Under cold conditions, the reaction of aniline with nitrous acid results in the formation of benzene diazonium salt. NH + Nano, + 2HC1 273K V (Aniline) NCE TOT + NaCl, + 2H20
What are the steps involved in converting aniline to iodobenzene?
In the process of converting aniline to idobenzene, it acts as a catalyst in the reaction. This results in the creation of a chemical known as benzenediazonium chloride, which is an intermediate compound. Iodobenzene is produced when Benzenediazonium chloride is subjected to a chemical reaction in the presence of potassium iodide as a catalyst. This results in the creation of the compound.
How exactly does aniline get made from benzoic acid?
- When benzoic acid is treated with thionyl chloride, benzoyl chloride is produced. Benzamide is then produced when benzoyl chloride is treated further with ammonia.
- Aniline is produced through the reaction of benzamide with bromine and sodium hydroxide. This process is known as the Hoffmann bromamde degradation.
What are the steps involved in converting aniline to phenol?
So, we are able to transform aniline into phenol by first treating aniline with sodium nitride and hydrochloric acid, which produces benzene diazonium salt. This, in turn, produces phenol when it reacts with water. Notice that phenol is produced as a result of the reaction. Hence, the process in question is one that prepares phenol.
How do you get aniline ready to use?
Commercial aniline can be produced either through the hydrogenation of nitrobenzene via a catalytic reaction or through the reaction of ammonia with chlorobenzene. The elimination of nitrobenzene can also be accomplished by dissolving iron borings in an acidic solution. Aniline, a primary aromatic amine, is a weak base that, when combined with mineral acids, results in the formation of salts.
When amide is heated with sodium hydroxide, what type of gas is produced?
When ethanamide and sodium hydroxide solution are heated together, ammonia gas is produced, and what’s left over is a solution that contains sodium ethanoate. An unidentified organic chemical is determined to be an amide if, after being treated with a solution of sodium hydroxide, it emits ammonia upon heating but does not do so promptly when exposed to cold temperatures.
In the presence of sodium hydroxide, what byproduct will the reaction between benzamide and bromine produce?
There will be a carbon-nitrogen rearrangement produced as a result of the reaction of acetamide with bromine and NaOH solution. This observation was made by a researcher by the name of Hoffman.
Is benzamide soluble in water?
The chemical formula for benzamide is C6H5C(O)NH2, and it appears in the form of a white solid. It is the most straightforward amide derivative that may be made from benzoic acid. It dissolves only marginally in water but is soluble in a wide variety of organic solvents.
What kind of a reaction takes place when aniline and nitrous acid meet at a low temperature?
During the reaction between aniline and nitric acid (HNO2), the nitrosonium ion of the nitric acid attacks the amine component of the aniline and transforms it into diazonium ion.
What results are seen when aniline is subjected to HNO2 treatment?
Nitrous acid, when applied to aniline, results in the formation of diazonium ion. Following additional treatment with dilute acid, a hydrolysis reaction will take place. Full solution: In this reaction, aniline serves as the reactant, and nitrous acid, denoted by the chemical formula [textHNtextO_text2], is provided to us as the reagent. and dilute acid.
What kind of reaction took place when aniline was exposed to HNO2?
At lower temperatures, such as 0-50 degrees Celsius, the reaction of aniline with aqueous nitrous acid (HNO2) produces benzenediazonium chloride. If the temperature of the aqueous solution is kept at room temperature, benzene diazonium chloride will hydrolyze easily into phenol. Only at very low temperatures does benzene diazonium retain its stability.
What are the steps involved in converting aniline to toluene?
Following the formation of benzene diazonium chloride via treatment with sodium nitrite in hydrochloric acid at a temperature of 423 K, the compound is then hydrolyzed using weak acid benzene. To create toulene, benzene is subjected to treatment with aluminum chloride.
Which of the following reactions is the most efficient way to convert aniline to benzonitrile?
Benzene diazonium chloride is produced when aniline is treated with NaNO2 and HCl. This product is then reacted with CuCN/KCN to replace N2Cl with CN in a process known as Sandmeyer’s Reaction, which results in the formation of benzonitrile.
What exactly is the function of benzonitrile?
Benzonitrile is an odorless liquid that has the consistency of oil and smells like almonds. Nitrile rubber, speciality lacquers, resins, polymers, and metal salts can all be dissolved in it because of its solvent properties.
What are the steps involved in converting aniline to cyanobenzene?
Aniline undergoes a reaction with NaNo2 and HCl, which results in the formation of benzene diazonium chloride. After further treatment with CaCN, the resulting compound is cyanobenzene.
What are the steps involved in converting aniline to p nitroaniline?
When aniline is treated with acetoacetate, the resulting substance is called nacetyl aniline. This, when subjected to H2SO4/HNO2/CH3COOH, will result in the production of paranito nacetyl aniline, which, when subjected to hydrolysis, will result in the production of para nito aniline.
Which reagent is utilized during the process of converting aniline into fluorobenzene?
Initially, aniline is made to react with NaNO2 in the presence of HCl, which results in the formation of “benzene diazonium chloride.” Benzene diazonium chloride is next reacted with fluoroboric acid (HBF4), which results in the formation of fluorobenzene coupled with the release of hazardous BF3.
