(D) Interstitial compounds are formed when small atoms like $H, B, C, N,$ etc.,are trapped inside the crystal lattice of transition metals.These compounds exhibit the following properties:$1$. They are much harder than the pure metal.$2$. They have higher melting points than the pure metal.$3$. They retain metallic conductivity.$4$. They are chemically inert (not reactive).Therefore,the statement that they are chemically reactive is incorrect.
