The p-Block Elements - Part2
A
$I^{-}>Br^{-}>Cl^{-}>F^{-}$
100%
B
$I^{-}>Br^{-}=Cl^{-}>F^{-}$
0%
C
$I^{-}=Br^{-}=Cl^{-}>F^{-}$
0%
D
$I^{-}=Br^{-} < Cl^{-}=F^{-}$
0%
Solution:
Applying Fajan's rules:
Larger the anion, more the polarization of electron density towards cation.
$I^{-}>Br^{-}>Cl^{-}>F^{-}$
