Doubt from acidic and basic strength

But @Shaquib wouldn't there be a hydrogen bond between H and O of nitro group which will decrease it's acidic character.

See what your saying is absolutely right but there is one difference
We consider h- Bonding when we have to tell acidic strength between ortho/ para position.

Apart from this we will consider only electron withdrawing property of NO2.
