The generation of the electrophile for the nitration of benzene involves reacting concentrated nitric acid and concentrated sulfuric acid according to the equation:
HNO3+2H2SO4→NO2++H3O++2HSO4− \text{HNO}_3 + 2\text{H}_2\text{SO}_4 \rightarrow \text{NO}_2^+ + \text{H}_3\text{O}^+ + 2\text{HSO}_4^- HNO3+2H2SO4→NO2++H3O++2HSO4−Which statement is correct?
H2SO4\text{H}_2\text{SO}_4H2SO4 acts as a Brønsted-Lowry acid.
H2SO4\text{H}_2\text{SO}_4H2SO4 acts as a Brønsted-Lowry base.
H2SO4\text{H}_2\text{SO}_4H2SO4 acts as an electrophile.
H2SO4\text{H}_2\text{SO}_4H2SO4 acts as a reducing agent.
