Question

hey friends plz help

what is role of H2so4 in nitration of benzene??????
plzzzzzz☜☜☜❤​

Answer 1

Sulfuric Acid Activation of Nitric Acid. The first step in the nitration of benzene is to activate HNO3with sulfuric acid to produce a stronger electrophile, the nitronium ion. Because the nitronium ion is a good electrophile, it is attacked by benzene to produce Nitrobenzene.

Answer 2

$<b><u>The source of the nitronium ion is through the protonation of nitric acid by sulfuric acid, which causes the loss of a water molecule and formation of a nitronium ion.$

The first step in the nitration of benzene is to activate HNO3 with sulfuric acid to produce a stronger electrophile, the nitronium ion.

Because the nitronium ion is a good electrophile, it is attacked by benzene to produce Nitrobenzene.
