In a structure, A atoms have fcc arrangement B atoms occupy all the tetrahedral sites and C atoms occupy half the octahedral sites. The formula of the compound is

A

`A_(2)B_(2)C_(2)`

B

`A_(2)B_(4)C`

C

`AB_(2)C`

D

`A_(4)B_(2)C`

Text Solution

Verified by Experts

The correct Answer is:
2
No. of 'A, atoms=x
no of 'B' atoms=2x (`because` tetrahedral holes are double the no. of spheres)
