(X = Cl, Br, I) is :
Choose an option
Show full solutionCorrect option: D
Correct answer
DBeX2
Step-by-step explanation
According to Fajan’s rule, when the size of cation is less then the
covalent character would be more for the cation.
Since Be2+ has minimum size among given cation, therefore, BeX2 would be most covalent among given alkaline with metal halides
Since Be2+ has minimum size among given cation, therefore, BeX2 would be most covalent among given alkaline with metal halides
