Q. Arrange the following in increasing order of covalent character $- NaCl, MgCl_{2}, AlCl_{3}$

Chemical Bonding and Molecular Structure

Solution:

Cartion size is decreasing in the order :
$Na^{+} > Mg^{2+}>Al^{3+} $
$Al^{3+} $ has maximum polarisation effect and $Na^+$ has minimum polarisation effect.
The covalent nature is in the order:
$ AlCl_{3} > MgCl_{2} > NaCl$
