JEE Main 2023 — Solid State Question with Solution

JEE Main 2023 (25 Jan Shift 1)

Question

A cubic solid is made up of two elements X and Y. Atoms of X are present on every alternate corner and one at the center of cube. Y is at 13rd of the total faces. The empirical formula of the compound is

Show full solutionCorrect option: B
Correct answer
BX1.5Y

Step-by-step explanation

The share of the atom present at corner of the cube is 1/8. The share of the atom at face centre is 1/2. Hence, the molecule can be represented as follows,

X4×18+1×1Y6×13×12

⇒X12+1  Y1

⇒X23  Y1

⇒X1.5  Y1(Empirical formula)

⇒X3  Y2.
