    For d-electron, the orbital angular momentum is

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

    B)  \[\frac{\sqrt{2}h}{2\pi }\]

    C)  \[\frac{h}{2\pi }\]

    D)  \[\frac{2h}{\pi }\]

    Correct Answer: A

    Solution :

     Angular momentum \[=\sqrt{l(l+1)}\frac{h}{2\pi }\] For d-orbital;\[l=2\] Angular momentum\[=\sqrt{2(2+1)}\frac{h}{2\pi }\] \[=\sqrt{6}\frac{h}{2\pi }\]
