A) \[{{A}^{+}}\]- Tetrahedral voids ; \[{{B}^{-}}\]- Corner
B) \[{{A}^{+}}\] - Corner and faces; \[{{B}^{-}}\] - Octahedral voids
C) \[{{A}^{+}}\] - Octahedral voids; \[{{B}^{-}}\]- Corner and faces
D) \[{{A}^{+}}\] - Corner and faces; \[{{B}^{-}}\] - Octahedral and tetrahedral voids
Correct Answer: C
Solution :
[c] AB is just like \[NaCl\]. Thus twelve \[{{A}^{+}}\] are at edges and 1 within body of fcc i.e. in octahedral voids and six \[{{B}^{-}}\] at faces and 8 at corner.You need to login to perform this action.
