Question

Phthalic acid and isophthalic acid have protons on two carboxy groups
that can be removed with base. (a) Explain why the pKa for loss of the
first proton (pKa1) is lower for phthalic acid than isophthalic acid. (b)
Explain why the pKa for loss of the second proton (pKa2) is higher for
phthalic acid than isophthalic acid.
