D

8

Text Solution

Verified by Experts

The correct Answer is:
D
Diamond is like ZnS (Zinc blende). Carbon forming ccp (fcc) and also occupying half of tetrahedral voids. Total no. of carbon atoms per unit cell =
`underset(("Corners"))(8xx1/8)+underset(("Face-centred"))(6xx1/2)+underset(("Tetrahedral void"))4=8`
