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

275.1pm

322.5pm

241.5pm

165.7pm

Text Solution

Verified by Experts

The correct Answer is:

For NaCl type structure, `r_(Na^(+))=0.414xxr_(Cl^(-))`
Therefore, `r_(Y^(-))=100/0.414`pm = 241.5pm.
