Mainly, the electrophile in the nitration of benzene is – nitronium ion (no2+).
Which is the electrophile in the nitration of benzene?
Actually, the electrophile is “nitronium ion” (NO2+) which is formed by reaction between nitric acid and sulphuric acid.
nitronium ion (NO2+) is formed by the reaction between nitric acid and H2SO4, sulphuric acid.
Nitronium ion NO2+ is a cation (removel of electron is known as cation).
it is created by removel of an electron from the nitrogen dioxide molecule.
this cation (NO2+) whichis a strong electrophile this phenomanon is called nitronium ion.
Nitronium ion can be prepared by the reaction of concentration nitric acid (HNO3) with concentration sulphuric acid. this reaction is very important for preparation of nitronium ion.
