JEE Main 2022 — Solid State Question with Solution

JEE Main 2022 (26 Jun Shift 2)

Question

In a solid AB,A atoms are in ccp arrangement and B atoms occupy all the octahedral sites. If two atoms from the opposite faces are removed, then the resultant stoichiometry of the compound is AxBy. The value of x is [nearest integer]

Correct answer
3

Step-by-step explanation

A forms ccp structure that means number of A atoms per unit cell →4

B atoms per unit cell →4 (Octahedral voids), as number of octahedral voids will be equal to number of atoms per unit cell.

A removed =2×12=1

A left =4-1=3

Formula becomes A3B4

x=3.
