Variation of pKa values among benzoic acids
A) Four benzoic acids are in the attached file along with four pKa values. Assign a pKa to each acid, and briefly explain the basis for your order.
b) While o-nitrobenzoic acid and p-nitrobenzoic acid differ significantly in pKa (as seen in part a), o-nitrophenol and p-nitrophenol do not; their pKa's are essentially the same (7.17 and 7.14). Give a brief explanation as to why this would be.
