CsBr has bcc structure with edge length ...

`CsBr` has `bcc` structure with edge length of `43 pm`. The shortest interionic distance between cation and anion is

A

`37.2`

B

`18.6`

C

`74.4`

D

`43`

Text Solution

Verified by Experts

The correct Answer is:
A
Body diagonal `= sqrt(3)a`
Distance between `Cs^(o+)` and `Br^(ɵ)` is
`("Body diagonal")/(2) = (sqrt(3)a)/(2) = (sqrt(3) xx 43)/(2) = 3.724`
