Question

arrange decreasing order of covalent character in LiCl,AlCl3,MgCl2​

Answer 1

Answer:

Explanation:

Nacl<Mgcl2<Alcl3

So ions are-Na+ ; Mg2+ ;Al3+

Because polarization is directly proportional to the charge

More charge=more polarization =more covalent nature.

Answer 2

Answer:

as we move from left to write covalent character increases so the order is as follow

alcl3 >mgcl2> licl
