What is the nitrating mixture?

The classic two-acid system called nitrating mixture has, for decades, been a mixture of nitric acid (nitrating agent) and concentrated sulfuric acid (acid catalyst), although several other acids have been used in the place of sulfuric acid. Scheme 1 Hughes–Ingold mechanism of electrophilic aromatic nitration.

Which of the following is used as nitrating agent?

Nitric acid is not only a nitrating agent but also an oxidizing agent. The nitration and the oxidation reactions both constitute a hazard. Nitric acid is itself a hazardous chemical, since it is not only a corrosive substance but also a strong oxidant.

What is nitrating mixture why it is so called?

Answer: ❐ => Nitrating mixture is the name given to the mixture of concentrated nitric acid and sulfuric acid, in a 1:1 ratio, used in the nitration of organic substances, such as aromatic compounds.

What is the role of conc HNO3 in nitrating mixture?

HNO3 acts as a base in the nitrating mixture and provides the electrophile NO2+ .

Is a nitrating mixture?

Nitrating mixture is a mixture of concentrated nitric acid (HNO3) or nitrogen oxides with inorganic compounds (H2SO4,BF3, and AlCl3) or organic compounds for example acetic anhydride.

What is Nitrating mixture one word?

a mixture of concentrated nitric acid or nitrogen oxides with inorganic compounds (H2SO4, BF3, and AlCl3) or organic compounds (for example, acetic anhydride).

What are Nitrating agents?

Nitration is used to apply nitrogen to a ring of benzene and can be used again in replacement reactions. A ring deactivator functions as the nitro group. It is very helpful to have nitrogen present in a ring so it can be used as a directing group as well as a masked amino group.

Which is most important Nitrating medium?

Which is the most important Nitrating medium? Explanation: A mixture on nitric acid and sulphuric acid give the most nitrating medium.

How do you make Nitrating mixture?

-Nitrating mixture is prepared in the laboratory by cooling a volume of concentrated sulfuric acid, usually in an ice bath. An equal volume of concentrated nitric acid is then slowly added to it keeping the solution at constant temperature.

What is Nitrating mixture how it is prepared?

By cooling an amount of condensed sulfuric acid, normally in an ice bath, the nitrate mixture is prepared. The term is often misapplied to the various processes in which nitrate esters are formed between alcohols and nitric acid. In order for a good electrophile to form, sulfuric acid is necessary.
