What is the process of electrolytic reduction?
Electrolytic reduction is a form of electrolysis in which electric current passes through an ionic substance in a molten or dissolved state causing the electrodes to react chemically and the materials to decompose. Some metals such as K, Na, Al are obtained through the process of electrolytic reduction.
Which of the following compound is formed on the electrolytic reduction of nitrobenzene?
Under weakly acidic conditions nitrobenzene on electrolytic reduction gives aniline but under strongly acidic conditions gives p-aminophenol.
What happens when nitrobenzene is reduced in basic medium?
When reduced in alkaline medium,nitro benzene forms some intermediate products like Nitrosobenzene and Phenyl hydroxylamine which undergo bi-molecular condensation reaction. In neutral medium if nitro benzene is reduced alongwith a common neutral reducing agent like Zinc dust,it forms Phenyl hydroxylamine .
How is nitrobenzene reduced to aniline give examples?
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.
What is the formula of nitrobenzene?
Nitrobenzene is an organic compound with the chemical formula C6H5NO2. It is a water-insoluble pale yellow oil with an almond-like odor. It freezes to give greenish-yellow crystals. It is produced on a large scale from benzene as a precursor to aniline.
What is electrolytic reduction explain with example?
The electrolytic reduction is a type of electrolysis in which electric current is pass through an ionic substance (molten or dissolved ) producing chemical reaction at the electrodes and a decomposition of the materials. Example: Sodium metal is obtained by the electrolysis of molten Sodium Chloride.
How does the process of electrolysis work?
Electrolysis is the process by which ionic substances are decomposed (broken down) into simpler substances when an electric current is passed through them. For electrolysis to work, the compound must contain ions. Covalent compounds cannot act as electrolytes because they contain neutral atoms .
What happens when nitrobenzene is reduced with zinc dust and aqueous ammonium chloride?
When reduced with a neutral reducing agent like zinc dust and aqueous ammonium chloride, nitrobenzene gives phenyl hydroxyl amine.
What happens when nitrobenzene reacts with bromine?
Nitrobenzene reacts with Br2 in the presence of FeBr3 to give m-bromonitrobenzene as major project.
How is nitrobenzene reduced in alkaline medium?
In a weakly acidic medium, nitrobenzene on electrolytic reduction gives aniline but under strongly acidic medium it gives p-aminophenol. In the alkaline medium, various mono and di-nuclear reduction products such as Azoxybenzene, Azobenzene are obtained. Therefore, the correct option is Option C, p-Aminophenol.
What happens when nitrobenzene is reduced to Sn \\ HCl?
The same things happen with nitrobenzene. As the following diagram shows, the reduction passes through the nitroso and hydroxylamine intermediates. The mechanism for the Sn\\HCl reduction involves reductive electron transfer of the nitro group while the tin is being oxidized. This diagram shows the electron transfers involved.
What is the percentage of nitrogen in nitrobenzene?
If the aqueous tension at 300 K is 25 mm the percentage of nitrogen in the compounds is, 33. The electrolytic reduction of nitrobenzene in strongly acidic medium produces Under weakly acidic conditions nitrobenzene on electrolytic reduction gives aniline but under strongly acidic conditions gives p-aminophenol.
What happens when nitrobenzene is added to soap?
Under weakly acidic conditions nitrobenzene on electrolytic reduction gives aniline but under strongly acidic conditions gives p-aminophenol. 34. Bithional is generally added to soap as an additive to function as a/an Bithional is added to soap to impart antiseptic properties.
Which is the first reaction of nitrobenzene to aniline?
They are the conversion of nitrobenzene to aniline in catalytic ( H X 2 / P d in ethanol) and acidic ( S n / H C l or F e / H C l) mediums respectively. The first reaction is called a catalytic reduction.
