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?

AThey have high melting points in comparison to pure metals.
BThey are very hard.
CThey retain metallic conductivity.
DThey are chemically very reactive.
Correct Answer

Solution

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.
