    The angular momentum of electrons in d orbital is equal to                                                   [NEET 2015 ]

    A)  \[\sqrt{6}h\]   

    B)  \[\sqrt{2}h\]     

    C)  \[2\sqrt{3}h\]     

    D)   \[0h\]

    Correct Answer: A

    Solution :

    Angular momentum of electron in d-orbital is
    \[=\sqrt{1+(1+1)}\frac{h}{2\pi }\] for d-orbital, \[I=2\]
    \[=\sqrt{2(2+1)}\Rightarrow h=\sqrt{6}h\]            \[\left( \because h=\frac{h}{2\pi } \right)\]
