    The most unlikely representation of resonance structure of p-nitrophenoxide is

    A)          

    B)

    C)                           

    D)  

    Correct Answer: C

    Solution :

    In structure (c), N atom forms five bonds, ie, has 10 electrons which is not possible due to absence of d-orbitals. Moreover, in this, nitrogen carry positive charge, hence because of these two Reason: structure (c) is highly unstable or we can say this structure possible.
