Chemistry Question on Unit Cells

A compound MpXqM_{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

A

MX

B

MX2MX_{2}

C

M2XM_{2}X

D

M5X14M_{5} X_{14}

Answer

MX2MX_{2}

Explanation

Solution

No.of Matoms=14×4+1=1+1=2=\frac{1}{4}\times4+1=1+1=2
No.of Xatoms =12×6+18×8=3+1=4=\frac{1}{2}\times6+\frac{1}{8}\times8=3+1=4
So, formula = M2X4=MX2M_{2} X_{4} =MX_{2}
