Distance between tetrahedral void and oc...

Distance between tetrahedral void and octahedral void in the lattice will be (a = edge length of unit cell) 

A

`(sqrt3a)/(4)`

B

`sqrt3a`

C

`(sqrt3a)/(2)`

D

`(sqrt3a)/(3)`

Text Solution

Verified by Experts

The correct Answer is:
A
In Fcc lattice octahedral void lies at the body centre tetrahedral void lies at `(1)/(4)`th of the body diagonal
`therefore` Body diagonal `=sqrt3a,(1)/(4)`of body diagonal `=(sqrt3a)/(4)`
