Isonitriles are stable, often naturally occurring, compounds that contain a divalent carbon. An example is axisonitrile-3, which can be isolated from a species of sponge and possesses antimalarial activity. Write a resonance form for axisonitrile-3 that satisfies the octet rule. Don’t forget to include formal charges.
