Question

`CsBr` has bcc stucture with edge length `4.3` pm .The shortest interionic distance in between Cs and Br is
A. 1.86 pm
B. 7.44 pm
C. 4.3 pm
D. 3.72 pm

Answer 1

Correct Answer - D
`CI^(-)` is pressent at conurs while `Cs^(+)` is present at Body centre, so minimum interatomic distance `=(sqrt(3a))/(2)=3.72"pm"`
