draw resonance structures for the conjugate base of
2,6dichloroibdophenol and use them to explain the differences in
the pka values
a value of 5.9 and is 10.000 times more 2,6-dichloroindophenol (see in Part III) has a pka value of 5.9 and is 10000 acidic than phenol (pKa =10). Draw resonance structures for the conjugate base of 26 dichloroindophenol and use them to explain the differences in the pKa values.

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
