Single Choice
Interstitial compounds are:
Anon-stoichiometric and are ionic in nature
Bnon-stoichiometric and are covalent in nature
Cnon-stoichiometric and are neither typically ionic nor covalent in nature
Correct Answer
Dstoichiometric and are neither ionic nor covalent in nature
Solution
An Interstitial compounds, or interstitial alloy, is a compound formed when an atom with a small enough radius sits in an interstitial 'hole' in a metal lattice. Since there is no proper proportional bonding in every space in the crystal lattice, it is is non-stoichiometric and also neither typically ionic and covalent.
