5. Which of the following statements about the interstitial compounds is incorrect?
[NEET 2013]
(a) They are chemically reactive.
(b) They are much harder then the pure metal.
(c) They have higher melting points than the pure metal.
(d) They retain metallic conductivity.
Show Answer
Solution:
- (a) Interstitial compounds are chemically inert.
In interstitial compounds small atoms like $H, B$ & $C$ enter into the void sites between the packed atoms of crystalline metal. They retain metallic conductivity and are chemically inert.
