    The decreasing order of bond angle is

    A)  \[N{{O}_{2}}>NO_{2}^{+}>NO_{2}^{-}\]

    B)  \[NO_{2}^{-}>N{{O}_{2}}>NO_{2}^{+}\]

    C)  \[NO_{2}^{+}>N{{O}_{2}}>NO_{2}^{-}\]

    D)  \[NO_{2}^{+}>NO_{2}^{-}>N{{O}_{2}}\]

    Correct Answer: C

    Solution :

                    The decreasing order of bond angle is as
    Species \[NO_{2}^{+}>\] \[N{{O}_{2}}>\] \[NO_{2}^{-}>\]
    Bond angle \[180{}^\circ \] \[135{}^\circ \] \[115{}^\circ \]
