- Single bond (C-C): ~1.54 Å

- Double bond (C=C): ~1.34 Å

- Triple bond (C≡C): ~1.20 Å

Ionic Bonds:

- Typically between 2.0 and 5.0 Å, depending on the ions involved.

Hydrogen Bonds:

- Typically between 1.5 and 3.0 Å, depending on the donor and acceptor atoms.

Metallic Bonds:

- Not well-defined due to the delocalized nature of valence electrons in metals, but typically around 2.5 Å for transition metals.

van der Waals Interactions:

- Typically between 3.0 and 5.0 Å, depending on the atoms or molecules involved.
