They can only be protonated by extremely strong acids, and their low reactivity makes them good solvents as in their aceto- form.  
One form of this functional group is the intermediate product in the Strecker synthesis of alpha-amino acids.  They can only be protonated by extremely strong acids, and their low reactivity makes them good solvents as in their aceto- form.  Commonly produced by the dehydration of primary amines, they possess many of the double bond features of imines and the triple bond features of alkynes.  FTP, name this functional group whose simplest member is cyanide and which consists of a carbon triple bonded to a nitrogen.
