• A. $PdC{l}_2$
• B. $N{H}_3$
• C. $ZnO$
• D. $TiH$

Answer 1

The correct option is D $TiH$

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. Examples: $TiH$, $F{e}_{3}H$ and $M{n}_{4}N$
