A compound M _ p X _ q has cubic close packing (ccp) arrangement of X . Its unit cell structure is shown below. The empirical formula of the compound is
Options
- AMX
- BMX ₂
- CM ₂ X
- DM ₅ X ₁₄
Correct answer
B. MX ₂
Step-by-step solution
No. of M atoms = 1 4 4+1=1+1=2 No. of X atoms = 1 2 6+ 1 8 8=3+1=4 So, formula =M₂ X₄=M X₂
