What happens when an isocyanide is heated for a long time?

Explanation

**Step-by-Step Solution:**

1. **Understanding Isocyanides**: Isocyanides, also known as isocyanates, are organic compounds that contain the functional group -N≡C. They are characterized by a carbon atom triple-bonded to a nitrogen atom.

2. **Heating Isocyanides**: When isocyanides are subjected to prolonged heating, they undergo a chemical transformation. This process is known as rearrangement.

3. **Rearrangement Process**: During the heating process, the structure of the isocyanide changes. The isocyanide undergoes a rearrangement reaction, which involves breaking and forming bonds to create a new compound.
