In the nitration of benzene with a mixture of conc. HNO_(3) and conc. H_(2)SO_(4) , the active species involved is :

Conc. H_(2)SO_(4) is not

In the nitration of phenol with a mixture of conc. HNO_3 and conc. H_2SO_4 , the active species involved is

Assertion(A):The nitrating reagent for carrying out nitration of benzene contains conc. H_(2)SO_(4) and conc. HNO_(3) . Reason: In the presence of conc. H_(2)SO_(4).HNO_(3) acts as a base and produces NO_(2)^(+) ions.

During nitratio of benzene using a mixture of conc. HNO_(3) and conc. H_(2)SO_(4) , function of conc. H_(2)SO_(4) is to increase the rate of reaction by increasing the concentration of NO_(2)^(+) according to following reaction. HNO_(3)+H_(2)SO_(4) rarr NO_(2)^(+)+HSO_(4)^(-)+H_(2)O Here nitric acid acts as

In the nitration of benzene with a mixture of concentrated HNO_(3) and concentrated H_(2)SO_(4) the active species involved is

Consider the nitration of benzene using mixed conc. H_(2)SO_(4) and HNO_(3) . If a large amount of KHSO_(4) is added to the mixture, the rate of nitration will be :
