Question

In which of the following pairs of structure are tetrahedral as well as octahedral voids respectively?

Answer 1

tetrahedral void number is 4 of oh void coordination number is 6

Answer 2

Welcome dear,

# Options are -
(A)BCC and FCC
(B)HCP and simple cubic
(C)HCP and CCP
(D)BCC and HCP


● Answer -
C) HCP & CCP

● Explanation -
- In crystal structure, both tetrahedral and octahedral voids are present in closed packing.


# In Hexagonal closed packing -
No of atoms => 12
No of tetra. voids => 12
No of octa. voids => 6

# In Cubic closed packing -
No of atoms => 4
No of tetra. voids => 8
No of octa. voids => 4


Hope this helps you...
