1.	The correct order of increasing polarising power of the cations in the following AlCl_(3) , MgCl_(3) , NaCl is
Answer» `AlCl_(3) lt MgCl_(3) lt NaCl` `MgCl_(2) lt NaCl lt AlCl_(3)` `NaCl lt MgCl_(2) lt AlCl_(3)` `NaCl lt AlCl_(3) lt MgCl_(2)` Solution :SINCE the polarising power INCREASES with increase in charge on the CATION ,therefore , polarising power increases in the order : `overset(+1)(Na)Cl lt overset(+2)(Mg) Cl_(2) lt overset(3+)(Al) Cl_(3)` Thus , option (c) is correct .
