Cyanide vs. Isocyanide: What's the Difference?

Edited by Huma Saeed || By Sara Rehman || Published on January 21, 2024
Cyanides are compounds with a carbon-nitrogen bond and a negative charge, while isocyanides have a reversed bonding order with a nitrogen-carbon bond.

Key Differences

Cyanides contain a carbon atom triple-bonded to a nitrogen atom (C≡N), whereas isocyanides have a nitrogen atom triple-bonded to a carbon atom (N≡C).
