Q6 / 155 · WBJEE 2026 · Chemistry
A compound contains two types of atoms A and B. Its crystal structure is a cubic lattice with 'A' atoms at the corner of the unit cells and 'B' atoms at the body centres. The simplest formula of the compound will be
- A$A_2 B$
- Correct answerB$AB$
- C$AB_2$
- D$AB_3$
Solution
Number of atoms of A per unit cell = $8 \times \dfrac{1}{8} = 1$
Number of atoms of B per unit cell = $1 \times 1 = 1$
The ratio of A to B is $1:1$.
The simplest formula of the compound is $AB$.
Answer: $AB$
Number of atoms of B per unit cell = $1 \times 1 = 1$
The ratio of A to B is $1:1$.
The simplest formula of the compound is $AB$.
Answer: $AB$
Hence, the correct answer is option: 'B'.
