    In a homonuclear molecule which of the following set of orbitals is degenerate?

    A) \[\sigma 2s\]and\[\sigma 1s\]                   

    B) \[\pi 2{{p}_{x}}\]and\[\pi 2{{p}_{y}}\]

    C)        \[\pi 2{{p}_{x}}\]and\[\sigma 2{{p}_{z}}\]

    D)        \[\sigma 2{{p}_{z}}\]and\[\pi 2{{p}_{x}}\]

    Correct Answer: B

    Solution :

    \[\pi 2{{p}_{x}}\]and\[\pi 2{{p}_{y}}\]or\[\pi 2{{p}_{x}}\]and\[\pi 2{{p}_{y}}\]orbitals have nearly equal energy and thus, are called degenerate orbitals.
