    \[A\xrightarrow[(ii)\,{{H}^{\oplus }}]{(i)\,NaOl}B\xrightarrow{SOC{{l}_{2}}}C\xrightarrow[NaOH]{{{C}_{6}}{{H}_{5}}N{{H}_{2}}}\]\[D\xrightarrow[\begin{smallmatrix}  Conc.\,\,{{H}_{2}}S{{O}_{4}} \\  (1\,\,equivalent) \end{smallmatrix}]{Conc.\,\,HN{{O}_{3}}}E\](Major) E can be -

    A)   

    B)  

    C)   

    D)   

    Correct Answer: B

    Solution :

     \[X-\underset{{}}{\overset{\begin{smallmatrix}  O \\  | \end{smallmatrix}}{\mathop{C}}}\,-C{{H}_{3}}\xrightarrow[{{H}^{\oplus }}]{NaOH}X-\underset{{}}{\overset{\begin{smallmatrix}  O \\  || \end{smallmatrix}}{\mathop{C}}}\,-OH\xrightarrow[{}]{SOC{{l}_{2}}}\] \[X-\underset{{}}{\overset{\begin{smallmatrix}  O \\  || \end{smallmatrix}}{\mathop{C}}}\,-Cl\xrightarrow[{}]{Ph-N{{H}_{2}}}X-\underset{{}}{\overset{\begin{smallmatrix}  O \\  || \end{smallmatrix}}{\mathop{C}}}\,-NH-PH\]
