Q. Among the following the maximum covalent character is shown by the compound.
A) $FeCl_{2}$
B) $SnCl_{2}$
C) $AlCl_{3}$
D) $MgCl_{2}$
Explanation
(c)
In all the given compounds, anion is same$(Cl^{-})$, hence polarising power is decided by size and charge of cation. $Al^{3 +}\$with maximum charge and smallest size has maximum polarising power hence, $AlCl_{3}$ is maximum covalent.
