A) hcp lattice - A, \[\frac{2}{3}\] Tetrahedral voids - B
B) hcp lattice - A, \[\frac{1}{3}\] Tetrahedral voids - B
C) hcp lattice - B, \[\frac{2}{3}\] Tetrahedral voids - A
D) hcp lattice - B, \[\frac{1}{3}\] Tetrahedral voids - A
Correct Answer: A
Solution :
Formula of the compounds No. of octahedral voids are equal to the number of atoms forming lattice A occupy octahedral void i.e., 2/3 of them B forms crystal lattice \[{{A}_{2/3}}B\Rightarrow {{A}_{2}}{{B}_{3}}.\]You need to login to perform this action.
