4-nitrophenol characterization


Why would 4-nitrophenol form a white precipitate in a halogen test using silver nitrate and nitric acid if there is no halogen in its structure?

Edit: edited title for better indexing. Mitch

I don't think it should. Could you take a melting point of the precipitate to see if it is an Aryl halide. Or even a boiling point of the nitro compound to make sure it is what you think it is?

You might be knocking it out of solution;  add a little ethanol and see if it dissolves/clarifies.

Are you sure it's not silver nitrite?  Silver nitrite is used in nitrating aromatic rings in the Victor Meyer reaction.

perhaps it's insolubility at play?
