Nitrobenze on electrolytic reduction in strongly acidic medium gives 2.1k LIKES. Under weakly acidic conditions nitrobenzene on electrolytic reduction gives aniline but under strongly acidic conditions gives p-aminophenol. Correct option (c) aniline. CBSE has reduced the syllabus for class 10 & 12 exam 2021, date sheet can release soon. of Parallelograms and Triangles, Introduction More the number of alkyl group attached with the carbon atom carrying the positive charge greater would be the tendency to stabilise positive charge via inductive effect, and hence more stable. Chemistry. Expressions and Identities, Direct Can you explain this answer? Also write chemical equations of the reactions involved. Due to the presence of benzene group, there is more resonance possibility than others hence it forms a more stable compound. Electroosmosis may be defined as a phenomenon in which the molecules of the dispersion medium are allowed to more under the influence of an electric field whereas colloidal particles are not allowed to more.Tyndall effect is the scattering of light by sol particles, which cannot be affected by change on them, The reaction of C6H5CH=CHCH3 with HBr produces.

On electrolysis of dil.sulphuric acid using Platinum (Pt) electrode, the product obtained at anode will be: An element has a body centered cubic (bcc) structure with a cell edge of 288 pm. In weakly acidic medium, aniline is obtained whereas in alkaline medium, various mono and di-nuclear reduction products (such as nitrosobenzene, phenylhydroxylamine, azoxybenzene, azobenzene and hydrazobenzene) are obtained. NCERT RD Sharma Cengage KC Sinha. The sodium pump is also known as a sodium Potassium pump. The possible alkene is : Assuming complete ionization, same moles of which of the following compounds will require the least amount of acidified $\ce{KMnO4}$ for complete oxidation ? Under weakly acidic conditions aniline are produced but under strongly acidic medium produces p-aminophenol. Which of the following set of molecules will have zero dipole moment ? Explanation : Electrolytic reduction of nitrobenzene in weakly acidic medium gives aniline but in strongly acidi c medium it gives p-aminophenol through the acid-catalysed rearrangement of the initially formed phenylhydroxylamine. The secondary amine forms dialkyl sulphonamide which is insoluble in alkali. Practice and master your preparation for a specific topic or chapter. Books. Describe the method for the identification of primary, secondary and tertiary amines. © 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.
