a)CaI2
b)CaF2
c)CaBr2
d)CaCl2

Answer 1

Answer:

CaI2

Explanation:

According to Fajan's Rule : If the size of anion increases for a given cation then ionic character decreases with the increase in the size of anion .

Now here the cation is fixed ( Ca2+)

and the biggest anion here is I2-

hence the ionic nature will be lowest in CaI2
