# The statement that is INCORRECT about the interstital compound is:Option 1)They are chemically reactiveOption 2)they are very hardOption 3)they have metallic conductivityOption 4)they have high melting point

Incorrect option:- Interstitial compounds are very reactive.

The compounds formed when small atoms of H, C or N get trapped the crystal lattice of metals are known as interstitial compounds.

$\rightarrow$ These compounds are very hard

$\rightarrow$ these compound are chemically inert in Nature

$\rightarrow$They have a high melting point, higher than that of the parent transition metals.

Option 1)

They are chemically reactive

Option 2)

they are very hard

Option 3)

they have metallic conductivity

Option 4)

they have high melting point
