NEETChemistryPeriodic Table and PeriodicityMCQ+4 / −1
Among the following which one has the highest cation to anion size ratio ?
  1. A
    CsI
  2. B
    CsF
  3. C
    LiF
  4. D
    NaF
View written solutionFree

Correct answer: B

The ratio in cation and anion size will be maximum when the cation is largest size and the anion is smallest size. So among the given species, Cs+ has maximum size among given cations and F- has smallest size among the given anions, So Cs/F has highest rc/ra
