QJEEM11Ch95f0: JEE Main 2011 Chemistry - Class 11 JEEM11Ch95f0 Solution: Among the following the maximum covalent character is shown by…

Charge of cation/Size of cation is called polarising power.

$\therefore$ (i) Polarising power $\propto$ charge of cation

(ii) Polarising power $\propto$

1

size of cation

Here the AlCl₃ is satisfying the above two conditions i.e., Al is in +3 oxidation state and also has small size. So it has more covalent character.
