Question

Among NaCl, BeCl2, AlCl3 which one is more covalent? Justify your answer.

Answer 1

Alcl3.

Now according to Fajan's rule the compound having the smallest cation and the largest anion will be most covalent. As we know that more the number of electrons lost , greater will be the electrostatic force of attraction between the valence shells and the nucleus therefore decreasing its size. Hence, the answer here will be :

AlCl3> BeCl2> NaCl....
