LiCl has rock salt structure, with an edge length of `6.0A^(@)`. If anions are in contact, the inoic radius of chloride ion is

A

`2.12A^(@)`

B

`1.82A^(@)`

C

`4.24A^(@)`

D

`3.68^(@)`

Text Solution

Verified by Experts

Face diagonal `=sqrt(2)a=sqrt(2)xx6=8.484`
Also face diagonal =4r
`r4=8.484 A^(@)rArrr=(8.484)/(4)=2.121A^(@)`
