Ethyllithium is the only alkyllithium that would react with acetic acid to form 2-butanone. The reaction proceeds via a nucleophilic addition of the ethyllithium to the carbonyl group of acetic acid, followed by a proton transfer to give the alkoxide intermediate. The alkoxide intermediate then undergoes a second proton transfer to give 2-butanone.
