Task: Text Categorization
Input (English): An aldehyde can be converted to one of these compounds by first being converted to an oxime and then undergoing dehydration. In turn, these compounds can be reduced to aldehydes by treatment with stannous chloride and hydrochloric acid, followed by hydrolysis. Immediate hydrolysis in the presence of an acid or a base yields their corresponding carboxylic acid and they can also be reduced, in the presence of lithium aluminum hydride, to primary amines. FTP, name these organic compounds characterized by a carbon triple bonded to a nitrogen.
Output (English): Science
