Role of HNO3 in nitration of benzene

  • #1

Homework Statement


in this case, the HNO3 can be dissociated into NO2+ and OH- ion. what makes it a proton donor. p/s : the ans is HNO3 is a proton donor for this question.


Homework Equations





The Attempt at a Solution



since the HNO3 can be dissociated into NO2+ and OH- ion, why it 's called as proton donor (acid), i would called it as alkaline... can someone explain on this plaese?

I do not see how ##HNO_3## could act as a proton donor when clearly a stronger acid is present.

You got the nitric acid dissociation into NO2+ wrong - OH- is not between products.

Hint: actually it is not HNO3 that dissociates into NO2+.

Psst... hydroxide does not function well as a leaving group. So, why do you need the sulfuric acid for? Could it help create a good leaving group?
