Predict the formulas of titanium hydride and titanium carbide formed by saturating the titanium latt — Solid State Chemistry Question

💡 Solution & Explanation

FCC has 4 Ti atoms, 8 tetrahedral voids, and 4 octahedral voids. Saturating tetrahedral voids with H gives $\text{Ti}_4\text{H}_8 \implies \text{TiH}_2$. Saturating octahedral voids with C gives $\text{Ti}_4\text{C}_4 \implies \text{TiC}$. Therefore, correct answer is B.
