The interionic distance for cesium chloride crystal will beA. aB. a/2C. `sqrt3 a//2`D. `2a//sqrt3`

Answer» Correct Answer - C
CsCl have simple cubic structure. In this structure body idagenal of simple cube `sqrt3 a = 2 xx (r_(CS^(+)) + r_(Cl^(-)))` So interionic distance `= 2 xx (r_(CS^(+)) + r_(Cl^(-)))`
