The correct order of increasing polarising power of the cations in the following is AlCl3,MgCl2, NaCl

Question

The correct order of increasing polarising power of the cations in the following is AlCl3,MgCl2, NaCl  (A)  AlCl3 < MgCl2 < NaCl  (B)  MgCl2 < NaCl < AlCl3  (C)  NaCl < MgCl2 < AlCl3  (D)  NaCl < AlCl3 < MgCl2

Tardigrade Admin · Accepted Answer

NaCl < MgCl2 < AlCl3 is the correct order of increasing polarising power of the cations. Because according to Fajan’s rules for cations, high charge and small size of the cation have more polarising power that is ability to distort electron density on an cation and induce partial covalent character Na+ < Mg2+ < Al3+

Q. The correct order of increasing polarising power of the cations in the following is $A lC l_{3}, M g C l_{2}, N a Cl$

$A lC l_{3} < M g C l_{2} < N a Cl$

$M g C l_{2} < N a Cl < A lC l_{3}$

$N a Cl < M g C l_{2} < A lC l_{3}$

$N a Cl < A lC l_{3} < M g C l_{2}$

Q. The correct order of increasing polarising power of the cations in the following is AlCl3​,MgCl2​,NaCl

AlCl3​<MgCl2​<NaCl

MgCl2​<NaCl<AlCl3​

NaCl<MgCl2​<AlCl3​

NaCl<AlCl3​<MgCl2​

Q. The correct order of increasing polarising power of the cations in the following is $A lC l_{3}, M g C l_{2}, N a Cl$

$A lC l_{3} < M g C l_{2} < N a Cl$

$M g C l_{2} < N a Cl < A lC l_{3}$

$N a Cl < M g C l_{2} < A lC l_{3}$

$N a Cl < A lC l_{3} < M g C l_{2}$
