Q25 / 90 · JEE Main 2021 (31 Aug Shift 2) · Chemistry

The empirical formula for a compound with a cubic close packed arrangement of anions and with cations occupying all the octahedral sites in $A_{x} B .$ The value of $x$ is (Integer answer)

Correct answer: 1

Solution

In

A_{x} B

Effective number of

B

atoms

= 4

(in CCP)
Effective number of

A

atoms

= 4

(all O.V.)
So formula of the compound

= A_{4} B_{4} = AB

So

x = 1

Hence, the correct answer is 1.
