What is the Difference Between Cyanide and Isocyanide?

Cyanide and isocyanide are isomers of each other, meaning they have the same molecular formula but different structures and properties. The key difference between them lies in the attachment of the CN group:

• Cyanide: Cyanide compounds have a CN group attached to an organic moiety through the carbon. Cyanides are highly polar and have a fairly pleasant odor. They are commonly used in mining for silver and gold, as well as in organic synthesis processes and pest control.
• Isocyanide: Isocyanide compounds have a CN group attached to an organic moiety through the nitrogen. Isocyanides are less polar than cyanides and have a very unpleasant odor. They are not as soluble in water as cyanides and do not form hydrogen bonds with water.

Some other differences between cyanides and isocyanides include:

• Cyanides tend to bind through their carbon atom or nitrogen atom in transition-metal chemistry, while isocyanides bind through the nitrogen atom.
• Cyanides are more commonly used as ligands in transition-metal chemistry, while isocyanides are less frequently encountered.

In summary, the main difference between cyanides and isocyanides is the attachment of the CN group, with cyanides having the CN group attached through the carbon and isocyanides having the CN group attached through the nitrogen. This difference in structure leads to variations in properties, such as polarity, solubility, and odor.

Comparative Table: Cyanide vs Isocyanide

Cyanide and isocyanide are isomers of each other, and they are organic compounds containing the cyanide anion (CN⁻). The key difference between the two lies in the attachment of the CN group. In cyanide compounds, the CN group is attached to the organic moiety through the carbon atom, while in isocyanide compounds, the CN group is attached to the organic moiety through the nitrogen atom. Here is a summary of the differences between cyanide and isocyanide in tabular form:
