AP Chemistry
8.6 Molecular Structure of Acids and Bases
A student compares the acid ionization constants (
\(K_a\)) of four carboxylic acids: fluoroacetic acid (\(\text{CH}_2\text{FCOOH}\)), chloroacetic acid (\(\text{CH}_2\text{ClCOOH}\)), bromoacetic acid (\(\text{CH}_2\text{BrCOOH}\)), and acetic acid (\(\text{CH}_3\text{COOH}\)). Which of the following lists the acids in order of decreasing acid strength (from strongest to weakest) and provides the correct explanation?
