What happens when aniline reacts with sulfuric acid?
We also know that aniline undergoes sulfonation reaction where it reacts with concentrated sulphuric acid resulting in the formation of anilinium hydrogen sulphate as an intermediate which on further heating with sulphuric acid at a temperature of about $453 – 473K$ or simply at ${200^\circ }C$, produces a para- …
Can aniline undergo sulfonation?
Anilines undergo the usual electrophilic reactions such as halogenation, nitration and sulphonation.
What happens when aniline is heated with concentrated H2SO4?
Aniline hydrogen sulphate on heating forms a mixture of o- and p-amino sulphonic acid.
When aniline is heated with conc H2SO4?
Which of the following compound will be formed when aniline reacts with h2so4?
For example, reaction of aniline with sulfuric acid at 180 °C produces sulfanilic acid, H2NC6H4SO3H.
What happens when aniline reacts with hno3 and h2so4?
Generally in the presence of nitric acid and sulphuric acid, aniline forms anilinium nitrate as an intermediate product and forms azobenzene nitrate. Hence, option C is the correct answer. Therefore, aniline when treated with a mixture of sulphuric acid and nitric acid gives a mixture of o-, m- and p- nitroaniline.
Is Sulphonation electrophilic substitution?
Nitration and sulfonation of benzene are two examples of electrophilic aromatic substitution. The nitronium ion (NO2+) and sulfur trioxide (SO3) are the electrophiles and individually react with benzene to give nitrobenzene and benzenesulfonic acid respectively.
Which catalyst is required for the Sulphonation of aniline?
Sulphonation. The vigorous reaction of sulphuric acid with aniline gives the formation of aniline hydrogen sulfate.
When aniline is heated with fuming sulphuric acid does it form?
Aniline-2,4-disulphonic acid.
When aniline is heated with fuming Sulphuric acid does it form?
When aniline is treated with fuming Sulphuric acid it forms?
What happens when aniline reacts with a mixture of conc sulphuric acid and conc nitric acid?[ Write equations involved?
Being a strong oxidising agent, HNO3 oxides aniline into tert oxidation product on treating it with conc. H2SO4 and HNO3. This is due to the reason that under strongly acidic conditions — NH, a group of aniline is converting into —NH3+(anilinium ion) which is m-directing, thus the major product is m-nitroaniline.
