Titanium crystallizes in a face centred cubic lattice. It reacts with carbon or hydrogen interstitially by allowing atoms of these elements to occupy holes in the host lattice. Hydrogen occupies tetrahedral holes but carbon occupies octahedral holes the formula of titanium carbide and hydride are
(1) \( \mathrm{TiC}_{2}, \mathrm{TiH}_{4} \)
(2) \( \mathrm{TiC}, \mathrm{TiH}_{2} \)
(3) \( \mathrm{Ti}_{3} \mathrm{C}, \mathrm{TiH}_{2} \)
(4) \( \mathrm{TiC}_{2}, \mathrm{TiH} \)
