    If the electron is visualized as a classical charged particle laterally rotating about an axis with angular momentum L, its magnetic dipole moment M then find the magnetic moment of \[{{K}_{3}}[Fe{{F}_{6}}]\] is

    A)  3.87 BM                      

    B)  4.89 BM

    C)  5.91 BM                      

    D)  6.92 BM

    Correct Answer: C

    Solution :

    \[F{{e}^{3+}}=\left[ _{18}Ar \right]\,4{{s}^{0}}\,3{{d}^{5}}\] \[n=5\] \[\mu \,\,=\,\,\sqrt{5\,\,(5+2)}\,\,=\,\,\sqrt{35}\,\,=\,\,5.91\,\,BM\]
