Question

The course of the reduction of nitro compounds takes place throught the following stages .
`C_(6)H_(5)NO_(2)rarrC_(6)H_(5)NOrarrC_(6)H_(5)NHOHrarr C_(6)H_(5)NH_(2)`
The nature of the final product depends mainly on the `pH` of the solution in which the reduction is carried out Aniline is the product when reduction is carried out in .
A. alkaline solution
B. neutral solution
C. acidic solution
D. strongly acid solution

Answer 1

Correct Answer - C
In acid solution (metal and acid) aniline is obtained via the nitrobenzene and nitrosobenzene free radical anions In strogly acidic solution (option4) the product is p-aminophenol formed by rerrangement of phenylhy droxylamine In netural solution (option2) e.g with zinc dust and ammonium chloride solution the main product of the reduction is phenylhydroxylamine In alkaline solution (option1) the compound obtained depends upon the nature of the reducing agent used The relatively complex compounds that may be obtained are azoxybenzene azobenzene and hydrazobenzene .
