Which of the following is the stronger acid?(a) Acetic acid(b) Propanoic acid(c) Isobutyric acid(d) 2,2-Dimethylpropanoic acidThe question was asked during an interview for a job.My question is taken from Carboxylic Acids Chemical Reactions topic in portion Aldehydes, Ketones and Carboxylic Acids of Chemistry – Class 12

Answer»

Correct CHOICE is (a) Acetic acid

Best EXPLANATION: As the size of alkyl group (electron releasing) increases, the electron density on the O of OH group increases, and makes release of H^+ ion more difficult. Thus, the release of proton from acetic acid will be easier compared to the higher acids, and is therefore the stronger acid.
