JEE Main & Advanced Chemistry Structure of Atom Question Bank Quantum number, Electronic configuration and Shape of orbitals

  • question_answer Orbital angular momentum for a d-electron is    [MP PET 2003]

    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 :

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