Question
Which of the following is not an interstitial compound?
✓
Answer
TiC$, \text{MoC}$ and $Fe_{0.82}O$ are interstitial compounds. However, $Cr_{2}O_{3 }$ is not an interstitial compound. Interstitial compounds are those compounds which are formed when small atoms like $H, C$ or $N$ are trapped inside the interstitial spaces in the crystal lattice of metals. They are usually non$-$stoichiometric in nature and cannot be represented by a definite composition and are neither typically ionic nor covalent.
