  • question_answer
    Maximum bond angle at nitrogen is present in which of the following?                                 

    A)  \[N{{O}_{2}}\]   

    B)         \[NO_{2}^{-}\]

    C)  \[NO_{2}^{+}\]               

    D)  \[NO_{3}^{-}\]

    Correct Answer: C

    Solution :

    Species Hybridisation Bond angle
    \[N{{O}_{2}}\]       \[sp\] Less than \[{{120}^{{}^\circ }}\]
    \[NO_{2}^{-}\]      \[s{{p}^{2}}\] \[{{115.4}^{{}^\circ }}\]
    \[NO_{2}^{+}\]      \[sp\](linear) \[{{180}^{{}^\circ }}\]
    \[NO_{3}^{-}\]      \[s{{p}^{2}}\] \[{{120}^{{}^\circ }}\]
    So, \[NO_{2}^{+}\] has maximum bond angle,
