    The number of bonding and anti-bonding respectively in \[CO\] molecule are

    A)  \[8,2\]                                 

    B)  \[2,8\]

    C)  \[4,2\]                                 

    D)  \[2,4\]

    Correct Answer: A

    Solution :

    The molecular orbital configuration of \[CO\] is as \[CO(6+8=14)\] \[=K{{K}^{*}}\,\,\sigma 2{{s}^{2}},\sigma *2{{s}^{2}},\pi 2p_{x}^{2}\approx \pi 2p_{y}^{2},\sigma 2p_{z}^{2}\] (* = antibonding orbitals) Number of bonding electrons = 8 Number of antibonding electrons = 2
