    Maximum bond angle at nitrogen is present in which of the following?                                                [NEET 2015 ]

    A)  \[N{{O}_{2}}\]           

    B)       \[NO_{2}^{-}\]

    C)  \[NO_{2}^{+}\]   

    D)       \[NO_{3}^{-}\]

    Correct Answer: C

    Solution :

               
    Species Hybridization 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,
