हिन्दीA compound is formed by cation C and anion A. The anions form hexagonal close packed (hcp) lattice and the cations occupy 75% of octahedral voids. The formula of the compound is _________.
Correct answer · Option 2
\( \text{C}_3\text{A}_4 \)
Explanation
Let number of anions (A) = N. Number of octahedral voids = N. Cations (C) = \( 0.75\text{N} = \frac{3}{4}\text{N} \). Formula is \( \text{C}_{3/4}\text{N} \to \text{C}_3\text{A}_4 \).
