Which of the following salt shows maximum covalent character?

A

`AlCl_(3)`

B

`MgCl_(3)`

C

`CsCl`

D

`LaCl_(3)`

Text Solution

Verified by Experts

The correct Answer is:
A
According to Fajan.s rule, as the charge on the cation increases, and size decreases, its tendency to polarise the anion increases. This brings more and more covalent nature to electrovalent compounds. Hence `AICI_(3)` shows maximum covalent character.
