Question

among the following the maximum covalent character is shown by the compound. a) FeCl2. b) SnCl2. c) AlCl3. d) MgCl2​

Answer 1

Answer:

AlCl3

Explanation:

As AlCl3 have Al³+ ion

Answer 2

$AlCl_{3}$ will have the maximum covalent character.

Explanation:

According to Fajan's rule, smaller is the charge of cation that is the cation will have high change and larger is the size of anion (small charge) more will be the covalent character of compound.

For example, Mg, Fe and Sn are all larger in size as compared to Al atom.

Therefore, $AlCl_{3}$ will have the maximum covalent character as compared to the compounds $FeCl_{2}$, $SnCl_{2}$, and $MgCl_{2}$.
