Question

The simplest formula of a solid having CCP arrangement for ‘A’ atoms in which alternate face centres are occupied by ‘B’ atoms and alternate edge centres are occupied by ‘C’ atom, is

Options

A.ABC
B.A4BC
C.A2BC
D.A4B2C

Solution

$Z_{A} = 4;Z_{B} = 2 \times \frac{1}{2} = 1;Z_{C} = 4 \times \frac{1}{4} = 1$

∴ Formula = A4BC
