Explain why the different positions have different pKa values,
using resonance structures.
The pka of phenol (C6H5OH) is 10.0. When a nitro group (NO) is attached to the ring, the pka decreases. Explain why the different positions have different pka values, using resonance structures. OH OH OH - ၄ NO, NO₂ 10. 0 pK, = 7 .23 8.35 7.1
