Interstitial compoundsHardQuestion 860008

Question

Interstitial compounds of transition metals (e.g., TiC, Fe₃C) are:
  1. A
    Hard, high-melting, chemically inert, with non-stoichiometric compositions
    Correct
  2. B
    Soft and reactive
  3. C
    Ionic compounds
  4. D
    Molecular compounds

Correct answer

Hard, high-melting, chemically inert, with non-stoichiometric compositions

Explanation

Interstitial compounds: small atoms (C, N, H) fit into interstitial voids of the transition metal lattice. Properties: very hard (reinforced structure), high melting points, retain metallic conductivity, chemically less reactive. TiN (gold colour), WC (cutting tools).
