If radius ratio for an ionic solid is 0.5248 and radius of cation is 0.95 ~A ^ . What is the radius of anion?

Options

  1. A1 45 ~A ^
  2. B1 81 ~A ^
  3. C1 20 ~A ^
  4. D1 60 ~A ^

Correct answer

B. 1 81 ~A ^

Step-by-step solution

Radius ratio = radius of cation / radius of anion 0.5248 = 0.95 / radius of anion Radius of anion = 1.81 A
