Ge‾H‾\text{Ge}_{\underline{\quad}}\text{H}_{\underline{\quad}}GeH
c.[1]
Germane (GeH4\text{GeH}_4GeH4) exists as small molecules and has a very low boiling point. What is the reason for the low boiling point of germane?
- Covalent bonds and intermolecular forces are weak.
- Only covalent bonds are weak.
- Only intermolecular forces are weak.
