Question

explain resonance structure of nitro- benzene

Answer 1

We never really need to know the number of resonance structures. The whole concept is qualitative, so we can't draw any quantitative conclusions from it. But if you want to do it anyway, then of course 1 and 5 are the same, while 2 and 4 are not (they have positive charges on different atoms).

Answer 2

Answer:

The resonating structure of nitrobenzene molecules are shown below. Explanation : Resonance structure : Resonance structure is an alternating method or way of drawing a Lewis-dot structure for a compound. These structures have the identical geometry but have different arrangements of the paired electrons.
