comment préparer Na2S2O4 au laboratoire
Few pieces of Metallic tin and conc HCl
Nitrobenzene has a nitro group.Benzene lacks that group
amine group ester nitro group
dns or dinitrosalicylic acid has a nitro group in its 3 and 5 positions each.maltose being a reducing sugar reduces the amino group at 3 rd carbon to amino grp and itself gets oxidized. the reduced product thus formed is 3-amino,5-nitro salicylic acid which is orange-red in color.
A Nitro group when attached to an organic molecule. Alone it is Nitric Oxide

Nitro group is electron withdrawing group like the COOH group. But still it is considered to be most easily reducible using a catalyst. As such there are no reports on sodium bicarbonate used directly, however I am using sodium bicarbonate to prevent the catalyst from getting oxidized during the reaction. I have not published the data so far.
Nitro group :)
The most reactive site of 2-nitro toluene is its 4th position which is para to methyl group and meta to nitro group.
Nitrobenzene has a nitro group.Benzene lacks that group
orientation of incoming Nitro group is destined by already present group on benzene ring . if already present group is electron donating group, it will promote electron density at ortho and para position and , therefore, nitro group is formed on ortho and para position.
amine group ester nitro group
dns or dinitrosalicylic acid has a nitro group in its 3 and 5 positions each.maltose being a reducing sugar reduces the amino group at 3 rd carbon to amino grp and itself gets oxidized. the reduced product thus formed is 3-amino,5-nitro salicylic acid which is orange-red in color.
because nitro group is ring deactivating group, nitration of nitro benzene is more difficult than benzene.
What would you expect the structure of the dinitro ester to be? (Consider the directing effects of the ester and the first nitro group on the addition of the second nitro group).
