Hi, I've got OCR "Chains, rings and spectroscopy" tommorow, and there's one thing I'm a bit unsure about.
For the mechanism of the nitration of benzene, you need to know an equation for the formation of the electrophile, NO2+.
Is it OK just to write: HNO3 + H+ --> NO2+ + H2O, or do you need to list the series of equations involving HNO3 and H2SO4?
P.S: Good luck to everybody taking the exam tommorow.
