Which of the following is the reactive intermediate formed in the electrophilic nitration of nitrobenzene with HNO₃ and H₂SO₄?

Question

Quizplus · Accepted Answer

The electrophilic nitration of nitrobenzene with HNO3/H2SO4 proceeds via an electrophilic aromatic substitution mechanism. The nitronium ion (NO2+) is the electrophile that attacks the aromatic ring. The reaction intermediate formed in this step is a sigma complex, which is resonance stabilized. The sigma complex then loses a proton to reform the aromatic ring, generating the nitro compound. The reactive intermediate in the electrophilic nitration of nitrobenzene with HNO₃ and H₂SO₄ is the nitronium ion (NO2+), which is formed by the reaction of HNO3 and H2SO4. Thus, the correct answer is choice B.
