Showing up as a characteristic "bite" around 3000 wavenumbers on an IR spec, FTP, what is this class of molecules that contains a carbon double bonded to an oxygen and single bonded to a hydroxyl group?
The Hell-Vollhard-Zellinsky reaction is used to brominate the alpha carbon of these molecules, and they can be synthesized via disproportionation of an aldehyde. Derivatives of them often go through addition-elimination reactions via a tetrahedral intermediate. Applying a solution of Grignard [Grin-yerd] reagents to dry ice is way to synthesize them, as is the hydrolysis of nitriles by sulfuric acid and heat. The butyric variety is responsible for the smell of rancid butter, and the formic variety was originally isolated from ants.
