    Primary nitro compounds when react with \[HN{{O}_{2}}\] forms crystalline solids which on treatment with NaOH gives

    A)                 Red solution      

    B)                 Blue solution

    C)                 White precipitate            

    D)                 Yellow coloration

    Correct Answer: A

    Solution :

               \[\underset{{{1}^{o}}\text{nitro}}{\mathop{R-C{{H}_{2}}-N{{O}_{2}}}}\,\xrightarrow{HN{{O}_{2}}}\underset{\text{Nitroloic acid}}{\mathop{R-\underset{N-OH\,\,\,}{\mathop{\underset{||}{\mathop{C}}\,-N{{O}_{2}}}}\,}}\,\]\[\xrightarrow{NaOH}\underset{\text{(Blood red)}}{\mathop{\underset{\,\,\,\,\,\,\,\,\,\,\,\,\,\,N-{{O}^{-}}N{{a}^{+}}}{\mathop{\underset{\,\,\,\,\,\,\,\,||}{\mathop{R-C\,}}\,\,-N{{O}_{2}}}}\,}}\,\]
