How do you convert aniline to bromobenzene?

Answer

1. Explanation :
2. Step 1 : First, primary aromatic amine (Aniline) react with the nitrous acid at low temperature, result in the formation of diazonium salt (benzenediazonium chloride).
3. Step 2 : Second, benzenediazonium chloride salt react with the copper bromide which result in the formtaion of bromobenzene.

How is aniline converted into benzene?

When aniline is treating with nitrating mixture or sodium nitrate in presence of a mineral acid like HCl, it results into benzene diazonium salt. When diazonium salt is treated with alcoholic KOH it gives phenol which can then be reduced in presence of Zn to give benzene.

How can you convert aniline to chlorobenzene?

Step 1: Sodium nitrite and hydrochloric acid is added to Aniline at very low temperatures (0 – 4ºC) to form a benzene diazonium ion (a diazonium salt). Step 2: This diazonium salt in presence of leftover hydrochloric acid is further treated with Copper Chloride to form Chlorobenzene.

How will you convert aniline to?

Thus, we can convert aniline to phenol by first treating aniline with sodium nitride and hydrochloric acid which gives benzene diazonium salt which in reaction with water gives phenol. Note: In the reaction, phenol is prepared. Thus, it is a preparation reaction of phenol.

How will you prepare bromobenzene from I benzene II aniline?

Explanation: To convert aniline to bromobenzene, few steps are followed:

1. Step 1 : Diazotization of aniline. During, this step aniline is converted into benzene diazonium chloride salt with the help of sodium nitrite and hydrochloric acid kept at a temperature of 0 – 5°C.
2. Step 2: Formation of bromobenzene.

How is aniline converted to toluene?

Aniline is treated with sodium nitrite in Hydro-chloric acid at temperature 423K to form benzene diazonium chloride followed by hydrolysis by weak acid benzene . Benzene is treated with aluminium chloride to form toulene.

How is chlorobenzene converted to phenol?

Explanation: When chlorobenzene is heated in the presence of concentrated sodium hydroxide (NaOH) at 300°C under high pressure, it results in the formation of sodium salt of phenol which n acidic medium leads to the formation of free phenol. This process is known as Dow’s process.

How phenol is converted into aniline?

Explanation:

1. To convert phenol ( ) into aniline ( ), it must be heated with ammonia in the presence of catalysts.
2. The catalyst used in this reaction is zinc chloride.
3. When phenol is heated with ammonia in the presence of zinc chloride as the catalyst at 473K, it loses the the hydroxyl group present in it.

How do you prepare phenol from aniline give equation?

Phenol is prepared from aniline. At the first step aniline is treated with HCL at around 273 to 278 K diazonium salts are obtained. These diazonium salts are very reactive. And when they are warm with water they get hydrolyzed to phenol.

How do you make bromobenzene?

Bromobenzene is prepared by the action of bromine on benzene in the presence of Lewis acid catalysts such as aluminium chloride or ferric bromide. Bromobenzene is used to introduce a phenyl group into other compounds. One method involves its conversion to the Grignard reagent, phenylmagnesium bromide.

How do you convert aniline to fluorobenzene?

Aniline can be converted to fluorobenzene by first converting it to diaazonium salt and then carrying out the Balz – Schiemann reaction . at 0–5 degree Celsius temperature forms benzene diazonium chloride ( Diazotisation reaction ) Step 2 : Reaction of BDC with HBF4 gives an intermediate product which on heating gives fluorobenzene .

How do you convert benzoic acid to aniline?

Step-2:—Conversion of benzoic acid into benzene. when benzoic acid is heated with soda lime,decarboxylation takes place to give benzene. Step-3:—Conversion of benzene into aniline. Benzene is heated with nitrating mixture to get nitrobenzene which is further reduced by Sn and HCl to form aniline.

What is the product of diazotization of aniline with copper(I) bromide?

Diazotization of aniline to form benezene diazonium salt which then treated with Copper (I) bromide will give bromobenzene. This is an example of Sandmeyer reaction. Tools for everyone who codes.
