Question:

Which of the following statements about the interstitial compounds is incorrect?

They are chemically reactive

They have higher melting points than the pure metal

They retain metallic conductivity

They are much harder than the pure metal

Solution:

The interstitial compounds are chemically inert as the impurity ions are present in the interstitial sites. The chemical reactivity of such compounds is similar to that of the parent compound. Hence, the option B is incorrect. Hence, the correct option is B.
