1)

A compound M_pX_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)

$MX_{2}$

C)

$M_{2}X$

D)

$M_{5}X_{14}$

Answer:

Option B

Explanation:

No. of M atoms = 1/4×4+1=1+1=2

No. of X atoms = 1/2 × 6+1/8×8 = 3+1 = 4
