    Which of the following has zero bond order?

    A)  \[He_{2}^{+}\]

    B)  \[H{{e}_{2}}\]

    C)  \[H_{2}^{+}\]

    D)  \[H_{2}^{-}\]

    Correct Answer: B

    Solution :

     \[H{{e}_{2}}(4)=\sigma 1{{s}^{2}},{{\sigma }^{*}}1{{s}^{2}}\] Bond order \[\frac{Number\text{ }of\text{ }bonding\,electrons-Number\text{ }of\text{ }antibonding\,electrons}{2}\] \[=\frac{2-2}{2}=0\]
