Chemistry Question on The solid state

Element 'B' forms ccp structure and 'A' occupies half of the octahedral voids, while oxygen atoms occupy all the tetrahedral voids. The structure of bimetallic oxide is :

A

A2BO4{ A_2BO_4}

B

A2B2O{ A_2B_2O}

C

A4B2O{ A_4B_2O}

D

AB2O4{ AB_2O_4}

Answer

AB2O4{ AB_2O_4}

Explanation

Solution

ZB=4,ZA=4×12=2,ZO=8Z_{B} = 4, Z_{A} = 4 \times\frac{1}{2} = 2, Z_{O} =8
Formula ; A2B2O8≡AB2O4A_{2}B_{2}O_{8} \equiv AB_{2}O_{4}
