These compounds will reduce ammoniacal silver nitrate, to precipitate out a silver mirror, in the Tollens test.
When reacted with resorcinol and hydrochloric acid, linear monosaccharides with this functional group do not form a red color in the Selwianoff test. Since Friedel-Crafts reactions cannot synthesize these compounds substituted with just a phenyl group, the Vilsmeier-Haack or Gattermann syntheses are used instead. One equivalent of DIBAL-H will reduce nitriles to them. In water, they usually undergo hydration to form geminal diols. Ozonolysis of monosubstituted alkenes will yield these compounds, as will oxidation with PCC of primary alcohols. These compounds will reduce ammoniacal silver nitrate, to precipitate out a silver mirror, in the Tollens test. For 10 points, name these compounds which have a carbonyl group at the end of a carbon chain, unlike ketones.
