What is the role of sulphuric acid in the synthesis of Nitro benzene?
Sulfuric acid acts as a catalyst in the synthesis of nitrobenzene by nitrating benzene. It facilitates the nitration reaction by protonating the nitric acid, making it a better electrophile for attacking the benzene ring. Sulfuric acid also helps in generating the nitronium ion, which is the active species involved in the nitration process.
What happens when benzene is treated with a mixture of concentrated sulphuric acid and nitric acid?
Benzene reacts with a mixture of concentrated sulfuric acid and nitric acid to undergo nitration, resulting in the substitution of one or more hydrogen atoms with nitro groups (-NO2) on the benzene ring. This reaction forms nitrobenzene as the primary product.
Reactant used to synthesize nitrobenzene?
Nitrobenzene is typically synthesized by nitration of benzene using a mixture of concentrated nitric acid and sulfuric acid as the nitrating agents. The reaction involves the substitution of a hydrogen atom on the benzene ring with a nitro group, resulting in the formation of nitrobenzene.
How will you prepare picric acid from benzene?
Picric acid can be prepared from benzene by first nitration to form nitrobenzene, followed by further nitration and subsequent treatment with a nitric/sulfuric acid mixture to yield picric acid. The process involves multiple steps and careful control of reaction conditions to avoid explosive hazards. It is important to handle picric acid with caution due to its potentially explosive nature.
Why direct nitration is used in picric acid?
in picric acid we cannot used direct nitration because of the phenol is very sensitive in oxidation of nitrate, to overcome this problem, we used a sulfuric acid added to phenol before the nitric acid. the reaction between NO2 and SO2 are reversible so the sulphate exchange with nitrate becoming tri nitrophenol

Is sulphuric acid a positive catalyst?
Sulphuric acid is not a positive catalyst. It is a strong mineral acid that can act as a catalyst in certain chemical reactions, but its role as a catalyst is not specific to promoting the forward reaction.

What are the chemicals of making sulphonic acid?
You react oil with Sulphur Trioxide via falling film reactor or react oil with Oleum (very strong Sulphuric Acid) in a CSTR reactor. The name of the process is Sulphonation or Sulfonation depending on English or American spelling style.

What is the reaction of benzene with HCl?
Nitration: H2SO4 C6H6 + HONO2 ---------> C6H5NO2 + H2O Nitric Acid Nitrobenzene Nitration: H2SO4 C6H6 + HONO2 ---------> C6H5NO2 + H2O Nitric Acid Nitrobenzene Nitration: .................H2SO4 C6H6 + HONO2 ---------> C6H5NO2 + H2O .....Nitric Acid ......Nitrobenzene
How will you convert benzene into p-nitrobromobenzene?
The Bromination of benzene in presence of Ferric chloride produces Bromobenzene the nitration of bromobenzene with dilute nitric acid gives ortho and para products which may be separated by physical means.
What is the function of sodium bicarbonate in esterification?
To remove the sulphuric acid (H2SO4) and carboxylic acid (RCOOH).
How will i convert benzene to aniline?
You nitrate the benzene with nitric and sulfuric acids, then catalytically hydrogenate the intermediate. But you're not going to do it at all if you can't raise the intermediate to 300 degrees C.
How will you prepare m-chloronitrobenzene from benzene in two steps?
Nitration: Benzene is nitrated to form nitrobenzene using a mixture of concentrated nitric acid and sulfuric acid as a nitrating agent. Chlorination: Nitrobenzene is then chlorinated using chlorine gas in the presence of a catalyst such as aluminum chloride to yield m-chloronitrobenzene.
