- Solved Why is p-nitrophenol more acidic than m-nitrophenol? - Chegg
The p-nitrophenol compound has three nitro groups (in the 2, 4, and 6 positions), while m-nitrophenol only has two nitro groups in the 3 and 5 positions) Resonance structures of the deprotonated phenol include structures with the negative formal charge in the meta positions but not the ortho or para positions
