A) \[P{{Q}_{2}}\]
B) \[{{P}_{2}}Q\]
C) PQ
D) \[{{P}_{2}}{{Q}_{2}}\]
Correct Answer: A
Solution :
Four atoms (P) contribute to one unit cell from ccp arrangement and 4 atoms (Q) from all the octahedral voids and 4 atoms (Q) from half of the tetrahedral void contribute to one unit cell. So, formula of solid is \[{{P}_{4}}{{Q}_{8}}\], so the simplest formula of the solid is \[P{{Q}_{2}}\]
