MCQ
The statement that is $INCORRECT$ about the interstitial compound is
  • A
    they have metallic conductivity
  • B
    they have high melting points
  • ✓
    they are chemically reactive
  • D
    they are very hard
✓

Answer

Correct option: C.
they are chemically reactive
c
In case of interstial compounds there is presence of small atoms (or impurity) in the lattice of metal. So interstial compounds are hard, high melting point and chemically inert.
