Question

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.
