MCQ
Which of the following is an interstitial compound?
- A$\mathrm{PdCl}_2$
- B$\mathrm{NH}_3$
- C$\mathrm{ZnO}$
- ✓$\mathrm{TiH}$
✓
Answer
Correct option: D.
$\mathrm{TiH}$
An interstitial compound is a compound that is formed when an atom with a small enough radius sits in an interstitial hole in a metal lattice. Examples of small atoms are boron, carbon and nitrogen. These compounds play an important role in industries.
