The transition metals sometimes form nonstoichiometric compounds. These compounds have
1 definite strucutres and definite proportions
2 indefinite structures and definite proportions
3 definite structures and indefinite proportions
4 indefinite structures and indefinite proportions

The type of holes occupied by \(\mathrm{\mathrm{H}}\) and \(\mathrm{\mathrm{C}}\) or \(\mathrm{\mathrm{N}}\) in interstitial compounds are respectively
1 Tetrahedral and octahedral
2 Octahedral and tetrahedral
3 Octahedral and octahedral
4 Tetrahedral and tetrahedral
Explanation:
Due to small size of \(\mathrm{\mathrm{H}}\) and large size of \(\mathrm{\mathrm{C}}\) or \(\mathrm{\mathrm{N}}\), occupy tetrahedral and octahedral holes, respectively.
