`CsCl`crystallizes in body centred cubic lattice. If `'a'` is its edge length then which of the following expressions is correct ?

A

`r_(Cs^(+))+r_(Cl^(-))=sqrt(3)/(2)alpha`

B

`r_(Cs^(+))+r_(Cr^(-))=sqrt(3)alpha`

C

`r_(Cr^(+))+r_(Cr^(-))=3alpha`

D

`r_(Cr^(+))+r_(Cr^(-))=(3alpha)/(2)`

Text Solution

Verified by Experts

The correct Answer is:
1
In CsCl structure, `Cs^(+)` ion is in contach with `Cl^(-)` ion at the nearest distance which is equal to `sqrt(3)(a)/(2)`
