`AICI_(3)` is covalent while `AIF_(3)` is ionic This can be justified on the basic of .

A

Valence bond theory

B

Crystal structure

C

Lettice energy

D

Fajan Rule

Text Solution

Verified by Experts

The correct Answer is:
d
Smaller the size of the anion ` (F^(-))` , lesser is its
polarization and hence more is the ionic character .
Thus ` AlCl_(3)` is covalent while ` AlF_(6)` is ionic - Fajan rule .
