A solid `AB` has `NaCl` structure. If the radius of the cation `A` is `100` pm, what is the radius of anion `B`?

A

100 pm

B

`173.5` pm

C

`241.5` pm

D

483 pm

Text Solution

Verified by Experts

The correct Answer is:
C
In NaCl type solid, `(r_(c))/(r_(a))=0.414`
`r_(a)=(r_(c))/(0.414)=(100)/(0.414)=241.5` pm
