Among the following which one has the highest cation to anion size ratio?

Options

  1. ACsI
  2. BCsF
  3. CLiF
  4. DNaF

Correct answer

B. CsF

Step-by-step solution

The order of size of given cations is Li ⁺ F ⁻ Thus, when the cation is largest and anion is smallest, the cation to anion size ratio is maximum. Hence, cation to anion size ratio is maximum for CsF.
