    Nitrogen molecule is chemically less active because of the presence of....... between two nitrogen atoms:

    A)  single bond    

    B)  double bond

    C)  triple bond     

    D)  coordinate bond

    Correct Answer: C

    Solution :

                    N (at.no. = 7) \[=1{{s}^{2}},2{{s}^{2}}2{{p}^{3}}\] \[{{N}_{2}}\]\[_{\times }^{\times }\text{N}_{\begin{smallmatrix}  \times  \\  \times  \end{smallmatrix}}^{\times }_{\begin{smallmatrix}  \bullet  \\  \bullet  \end{smallmatrix}}^{\bullet }\text{N}_{\bullet }^{\bullet }\]  or \[N\equiv N\] \[{{N}_{2}}\] molecule is less reactive due to the presence of high energy triple bond.
