One variety of them formed from secondary imines such as pyrimidine are named for Zincke. Two equivalents of these compounds yield a carboxylic acid and a primary alcohol in a disproportion reaction named for Cannizaro. They are characterized by an NMR shift of about 9 to 10 ppm, and their oxidation in the presence of a diamine-silver complex yields a "silver mirror" in the Tollens test. For 10 points, identify this functional group which features a carbon double bonded to an oxygen atom and single bonded to a hydrogen atom, exemplified by methanal and ethanal.
