$A_{2} B$ has antifluorite structure ( $B$ forms $FCC$ lattice and $A$ occupies tetrahedral voids). If all ions along any one body diagonal are removed, then new formula of compound will be:

Options:

Answer:

Solution:

On one body diagonal, $2 A$ -atoms(full contribution) $2 B$ -atoms $(\frac{1}{8} c o n t r i b u t i o n s)$ lie. So, new formula = $A_{8 - 2} B_{4 - \frac{1}{4}} = A_{8} B_{5}$
