Which of the following statement is not true about interstitial complexes?
A
Small atom like 
or 
are trapped inside crystal lattice
or are trapped inside crystal lattice B
They are usually non-stoichiometric
C
They generally 
retain metallic conductivity
retain metallic conductivity D
They are chemically very active
Text Solution
Verified by ExpertsThe correct answer is:
D
Interstitial compounds or non stoichiometric compounds are formed, when small atoms like 
are trapped inside the crystal lattice of metals. They are very hard and rigid and have high melting point, which are higher than those of the pure metals. They exhibit metallic conductivity like that of the pure metals. They aquire chemical inertness.
