    In a homonuclear molecule, which of die following sets of orbitals is degenerate?

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

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

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

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

    Correct Answer: B

    Solution :

    Orbitals having nearly same energy are called degenerate orbitals. Among the given, \[\pi 2{{p}_{x}}\] and \[\pi 2{{p}_{y}}\] orbitals are of equivalent energy, thus are called degenerate orbitals.
