Answer» NUCLEOPHILE during the reaction free radical during the reaction electrophile during the reaction catalyst during the reaction Solution :Electrophile `NO_(2)^(+)` is GENERATED by the help of `H_(2)SO_(4)`. In absence of `H_(2)SO_(4)` a nucleophile `NO_(3)^(-)` will be FORMED which will not helpful in electrophilic substitution.
