Nitration of benzene

Question 1

What does the nitration of benzene form?

Answer 1

= nitrobenzene
= and a H+ ion, regenerated acid catalyst

Question 2

What are the reagants for this reaction

Answer 2

= concentrared nitrioc acid, HNo3
= and concentrated sulfuric acid H2So4, catalyst
= electrophile:+ NO2

Question 3

How is the No2+ electrophile formed?

Answer 3

= HNo3 + 2H2SO4 => +No2 + 2H2SO4- + H3O+
= +H-OSo2OH, reacts with a nitric acid, this has a lone pair of electrons on the oxygen, 2 , this forms a OSO2OH and a H2ONo2
= the bond between the nitrogen and oxygen breaks firming +NO2 and H2O

Question 4

What is the mechanism for the nitration of benzene?

Answer 4

= +NO2 reacts with benzene, this forms a horse shoe shape, this must extent between 2 to 6 not any more
= the H+ breaks and electrons go to the delocalised ring
= this forms aH+ io

Question 5

What is the importance of this reaction?

Answer 5

= synthesising useful compounds, tnt
= formation of amines, dyes
=
