MCQ
Which is the most important contributing resonating structure of the following?

${\left[ {\begin{array}{*{20}{c}}
  {\,\,\,\,\,\,O} \\ 
  {\,\,\,\,\,\,||} \\ 
  {C{H_2} = N = O} 
\end{array}} \right]^\Theta }$

  • A
    $\begin{matrix}
       \,\,\,\,\,\,:\,\overset{\centerdot \,\,\centerdot }{\mathop{O}}\,{{:}^{\Theta }}\,\,  \\
       \,\,\,\,\,\,||\,\,\,\,  \\
       \overset{\oplus }{\mathop{C}}\,{{H}_{2}}-\underset{\centerdot \,\,\centerdot }{\mathop{N}}\,-\underset{\centerdot \,\,\centerdot }{\overset{\centerdot \,\,\centerdot }{\mathop{O}}}\,{{:}_{\Theta }}  \\
    \end{matrix}$
  • B
    $\begin{matrix}
       \,\,\,\,\,\,\,\overset{\centerdot \,\,\centerdot }{\mathop{O}}\,:\,\,\,  \\
       \,\,\,\,\,\,||\,\,\,\,  \\
       \overset{\Theta }{\mathop{C}}\,{{H}_{2}}-\underset{\oplus }{\mathop{N}}\,-\underset{\centerdot \,\,\centerdot }{\overset{\centerdot \,\,\centerdot }{\mathop{O}}}\,{{:}^{\Theta }}  \\
    \end{matrix}$
  • $\begin{matrix}
       \,\,\,\,\,\,\,\,\,\,\overset{\centerdot \,\,\centerdot }{\mathop{:O}}\,{{:}^{\Theta }}\,\,\,\,\,\,\,  \\
       \,\,\,\,\,\,\,\,|\,\,\,\,\,\,\,  \\
       C{{H}_{2}}=\underset{\oplus }{\mathop{N}}\,-\underset{\centerdot \,\,\centerdot }{\mathop{\overset{\centerdot \,\,\centerdot }{\mathop{O}}\,}}\,{{:}^{\Theta }}  \\
    \end{matrix}$
  • D
    $\begin{matrix}
       \,\,\,\,\,\,\,\,\,\,\overset{\centerdot \,\,\centerdot }{\mathop{:O}}\,{{:}^{\Theta }}\,\,\,  \\
       \,\,\,\,\,\,\,\,|\,\,\,\,  \\
       ^{\Theta }\overset{\centerdot \,\,\centerdot }{\mathop{C}}\,{{H}_{2}}-\underset{\oplus }{\mathop{N}}\,=\overset{\centerdot \,\,\centerdot }{\mathop{O}}\,{{:}}  \\
    \end{matrix}$

Answer

Correct option: C.
$\begin{matrix}
   \,\,\,\,\,\,\,\,\,\,\overset{\centerdot \,\,\centerdot }{\mathop{:O}}\,{{:}^{\Theta }}\,\,\,\,\,\,\,  \\
   \,\,\,\,\,\,\,\,|\,\,\,\,\,\,\,  \\
   C{{H}_{2}}=\underset{\oplus }{\mathop{N}}\,-\underset{\centerdot \,\,\centerdot }{\mathop{\overset{\centerdot \,\,\centerdot }{\mathop{O}}\,}}\,{{:}^{\Theta }}  \\
\end{matrix}$
