Interstitial compounds are formed when small atoms are trapped inside the crystal lattice of metals. Which of the following are the characteristic properties of interstitial compounds?
I. They have high melting points in comparison to pure metals.
II. They are very hard.
III. They retain metallic conductivity.
IV. They are chemically very reactive.
Choose the correct option.
I. They have high melting points in comparison to pure metals.
II. They are very hard.
III. They retain metallic conductivity.
IV. They are chemically very reactive.
Choose the correct option.
View answer and explanation
Correct option: A
I, II and III
Option A (I, II and III) is correct because interstitial compounds have high melting points, are very hard, and retain metallic conductivity, but they are chemically inert, not reactive.
