An illustration depicts the structures of four compounds. The first compound has a two-carbon chain, in which C 1 is double bonded to an oxygen atom and single bonded to an oxygen atom carrying a negative charge. A rightward arrow depicts the comparison of acidity of the compounds. The left end of the arrow is labeled, weakest acid and the right end is labeled, strongest acid. The second compound has a five-carbon chain, in which C 2 and C 4 are each double bonded to an oxygen atom and C 3 carrying a negative charge is single bonded to a hydrogen atom. The third compound has a three-carbon chain, in which C 2 is double bonded to an oxygen atom and C 3 carrying a negative charge is single bonded to two hydrogen atoms. The fourth compound has a two-carbon chain, in which C 1 carries a negative charge and single bonded to two hydrogen atoms, C 2 is bonded to three hydrogen atoms.
