    Orbital angular momentum for a d-electron is

    A) \[\frac{6h}{2\pi }\]        

    B) \[\frac{\sqrt{6}\,h}{2\pi }\]

    C) \[\frac{12h}{2\pi }\]      

    D) \[\frac{\sqrt{12}\,h}{2\pi }\]

    Correct Answer: B

    Solution :

    [b] We know that for d-electron  \[l=2.\]
                \[\mu =\sqrt{l(l+1)}\,\frac{h}{2\pi }\]; \[\mu =\sqrt{2\,(2+1)}\,\frac{h}{2\pi }\]
                \[\mu =\sqrt{2\,(2+1)}\frac{h}{2\pi }\]; \[\mu =\,\sqrt{6}\frac{h}{2\pi }.\]
