A solid compound XY has NaCl structure. ...

A solid compound `XY` has `NaCl` structure. If the radius of the cation is `100` pm, the radius of the anion `(Y^(-))` will be

A

275.1 pm

B

322.5pm

C

241.5 pm

D

165.7 pm

Text Solution

Verified by Experts

The correct Answer is:
C
Radius ratio of NaCI like crystal `(r^+)/(r^-) = 0.414`
`r^(-) = (100)/(0.414) = 241.5 `pm
