Question

In a hypothetical solid, ‘C’ atoms form CCP lattice. ‘A’ atoms occupy all tetrahedral voids and ‘B’ atoms occupy all octahedral voids, without disturbing the crystal. If a unit cell of the crystal is cut by a plane shown in the figure, then the cross section of this plane looks like

Options

A.
B.
C.
D.

Solution

None of the tetrahedral as well as octahedral voids will be in contact with other tetrahedral and octahedral voids, respectively.
