For 10 points, name this acid whose anion is isoelectronic with carbon monoxide and  contains a carbon-nitrogen triple bond.
This molecule has been synthesized by the Shawinigan or Fluohmic process, in which the heat of formation is provided by  electrical heating. Acetone and this molecule are consumed to produce methyl methacrylate. Ammonia must be removed  to prevent polymerization of this molecule in two synthetic methods for this molecule, the Degussa-developed BMA  process and Andrussow oxidation, which both require a platinum catalyst and consume methane and ammonia. This  molecule is added across the double bond of an aldose in the (*) Kiliani- Fischer synthesis to extend a monosaccharide by one  carbon. Reacting this compound with butadiene yields a precursor to nylon. When inhaled, this molecule inhibits cytochrome c  oxidase in the electron transport chain.
