Why Nitration of Phenol produces only 2-nitrophenol & 4-nitrophenol?!
Is it not possible for 3-nitrophenol to occur too?

You would get 3-nitrophenol but only a very very low yield compared to the 2 and 4 isomers. This is mainly due to the mesomeric effect:
The delocalisation of oxygen's lone pair into the aromatic system increases electron density at the 2 and 4 positions. These positions therefore are much better at attacking the nitronium ion than the 3 position is.
