As we learnt in

Nitration of phenol -

Yields ortho and para nitrophenols with dilute HNO3, which are separated by steam distillation.  Yield 2, 4, 6 - trinitrophenol / picric acid with conc. HNO3.

- wherein

 

 Phenol on reaction with conc.H2SO4  gives a mixture of o- and p- products and then at room temperature o- product is more stable, which on treatment with conc. HNO3 will yield o-nitrophenol. Since temperature is not mentioned o-nitrophenol is the only stable product. 

Correct option is 3.


Option 1)

nitrobenzene

Option 2)

2, 4, 6-­trinitrobenzene

Option 3)

o- nitropheno

Option 4)

p-nitrophenol
