Additionally, How do you convert nitrobenzene to Benzanilide? Answer: Nitrobenzene can be converted into benzoic acid as follows. Benzene diazonium chloride is treated with H₃PO₂ to give benzene. Benzene is reacted with CO and HCl in presence of anhydrous AlCl₃ to form benzene.
How do you make benzophenone oxime from benzophenone?
Benzophenone oxime has been prepared in quantity by treating an aqueous alcoholic mixture of benzophenone and hydroxylamine hydrochloride with hydrochloric acid,2 with sodium carbonate,3 with alcoholic potassium hydroxide,4 or with aqueous sodium hydroxide.
What is Benzanilide used for?
Benzanilide is used to make dyes, active pharmaceutical ingredients and perfumes. It is also used to study the influence of beta-cyclodextrin on photorearrangement of acetanilide, benzanilide and ethyl phenyl carbonate. Further, it is used as an amide model compound to study the reaction between the amide and epoxy.
Why is aniline converted to acetanilide?
Why is aniline converted into acetanilide before nitration? Answer: During direct nitration aniline is converted to anilinium ion which is ring deactivating and meta directing group. Hence, in order to retain it ortho/para directing group is converted into acetanilide.
Why is HCl used in acetylation of aniline?
It can be accomplished by adding requisite amount of concentrated HCl whereby the highly reactive amino function easily takes up a proton from the dissociation of HCl in water, get protonated to yield aniline hydrochloride that is water-soluble.
How is nitrobenzene reduced to aniline?
Nitrobenzene is reduced to aniline by Sn and concentrated HCl. Instead of Sn, Zn or Fe also can be used. … Then aqueous NaOH is added to the aniline salt to get released aniline. This reaction is called nitrobenzene reduction.
How do you convert benzene to Meta Bromo phenol?
For the conversion of Benzene to m-Bromophenol, we take the Benzene ring in the Presence of Nitration process such as HNO/H2SO4 that will give Nitrobenzene. This will again go in the Reaction with Br2 giving out the m-Bromonitro Benzene.
How do you convert aniline to p nitroaniline?
Nitration: Direct nitration of aniline yields (p-nitroaniline) a mixture of ortho, meta, and para nitroanilines. In an acidic medium the -NH2 group is protonated to the -N+H3 group which is meta-directing and deactivating. Hence, a considerable amount of m-nitroaniline is obtained.

What is the use of Acetanilide?
Acetanilide is mainly used as an intermediates for the synthesis of pharmaceuticals and as an additive in hydrogen peroxide, varnishes, polymers and rubber.
What is the purpose of acetanilide in the preparation?
Acetanilide is used as an inhibitor of hydrogen peroxide decomposition and is used to stabilize cellulose ester varnishes. It has also found uses in the intermediation in rubber accelerator synthesis, dyes and dye intermediate synthesis, and camphor synthesis.
Why is acetylation of aniline necessary prior to nitration?
Why is group of aniline acetylated before carrying out nitration? Answer: Due to the strong activating effect of group, aromatic amines readily undergo electrophilic substitution reactions and it is difficult to stop the reaction at the monosubstitution stage.
Why is aniline protected before nitration?
Answer: … The hurdles for the nitration of aniline are overcome by the protection of amino group by acetylation. The acetyl group reduces the reactivity of the ring and thus its oxidation does not occur easily with nitric acid HNO3.
What is the purpose of HCl in this reaction?
Abstract. Hydrochloric acid (HCl) is commonly used for the neutralization of alkaline agents, as a bleaching agent, in food, textile, metal, and rubber industries. It is neutralized if released into the soil and it rapidly hydrolyzes when exposed to water.
What happens when HCl is added to aniline?
HCl(aq) will react with aniline to form anilinium chloride, C6H7NH+Cl–, which is water-soluble.
