Per NCERT §9.5.5 nitration, the actual ELECTROPHILE that attacks benzene in HNO₃ + H₂SO₄ mixture is which species?
ANO₂ (neutral radical)
BNO⁺ (nitrosyl cation)
CHNO₃ (intact acid)
DNO₂⁺ (nitronium ion)
Answer & Solution
Correct answer: D. NO₂⁺ (nitronium ion)
NCERT §9.5.5: H₂SO₄ protonates HNO₃ → H₂O + NO₂⁺. The nitronium ion is the active electrophile.
