(i) No. of unpaired electrons in [Cr(H_{2}O)_{6}]^{3+} is 3.

                 The magnetic moment is given by : 

                                                                          =\ \sqrt{n(n+2)}

or                                                                       =\ \sqrt{3(3+2)}\ =\ \sqrt{15}BM

(ii) Similarly in   [Fe(H_{2}O)_{6}]^{2+} the number of unpaired electrons is 4.

                 So the magnetic moment : 

                                                              =\ \sqrt{4(4+2)}\ =\ \sqrt{24}BM

(iii) In the case of    [Zn(H_{2}O)_{6}]^{2+}   the number of unpaired electrons is 0. So its magnetic moment is also zero.

Thus   [Fe(H_{2}O)_{6}]^{2+}  has the highest dipole moment among all.
