Molecules of the title β-keto acid, 7-oxobicyclo[2.2.1]heptane-1-carboxylic acid, C8H10O3, exhibit chirality due to the bridgehead carboxyl group, which is partially ordered and has a slightly asymmetric conformation. The molecules form centrosymmetric hydrogen-bonded carboxyl dimers [O...O 2.639 (2) Å]. The title alkenoic γ-keto acid, (\pm)-7-oxobicyclo[2.2.1]hept-5-ene-2-endo-carboxylic acid, C8H8O3, also forms typical centrosymmetric hydrogen-bonded carboxyl dimers [O...O 2.660 (3) Å]. There is partial disorder of the carboxyl group in each compound.
