Question

Interstitial compounds are formed when small atoms are trapped inside the crystal lattice of
metals. Which of the following is not the characteristic property of interstitial compounds?

• A. They have high melting points in comparison to pure metals.
• B. They are very hard.
• C. They retain metallic conductivity.
• D. They are chemically very reactive.

Answer 1

The correct option is D They are chemically very reactive.

Interstitial compounds have high melting points in comparison to pure metals. They are very hard and retain metallic conductivity. They are chemically inert i.e. not reactive.
