Tollens\' reagent, [Ag(NH3)2] , is used to test for the presence of aldehydes. The reaction results in reduction of the silver ion to form a mirror of silver metal. Concurrently, the aldehyde is oxidized. Draw the structure of the organic product resulting from treatment of 3-methylbutanal with Tollens\' reagent, followed by treatment with acid.
