Nitroation of nitrobenzene results in

Nitration of nitrobenzene yields -

Nitration of nitrobenzene gives mainly m-dinitro benzene.

Write resonance structures to explain the nitration of nitrobenzene giving mainly m-dimitrobenzene.

Account for (a) Nitration of benzene is easier than nitration of nitrobenzene (b) Benzaldehyde undergoes condensation with nitro methane in presence of KOH (c) Nitromethane gives trichloro nitro methane on treatment with chlorine/NaOH while nitro ethane gives only dichloro ethane
