Question

In octahedral holes (voids)

Solution

Correct option is

A bi – triangular void surrounded by six spheres

 

The interstitial void formed by the combination of two triangular voids of the first and second layer is called octahedral void because this

is enclosed between six sphere, centres of which occupy corners of a regular octahedron.
