Which property from following is NOT exhibited by interstitial compound?
Options
- ATheir melting points are higher than pure metal.
- BTheir densities are less than parent metal.
- CTheir chemical properties are different than parent metal.
- DThese are hard and good conductors of heat and electricity.
Correct answer
C. Their chemical properties are different than parent metal.
Step-by-step solution
The compounds formed when small atoms of H , C or N get trapped inside the crystal lattice of metals is known as interstitial compounds. - The chemical properties of the parent transition metals are not altered during the formation of interstitial compounds. - These compounds have very high melting points, higher than that of the parent transition metals. - These compounds are very hard. The hardness of some borides is comparable to that of a diamond. - The conductivity exhibited by them is similar to their parent
