Question

The incorrect statement regarding the reaction given below is

• A. The product 'B' formed in the above reaction is p-nitroso compound at low temperature.
• B. The reaction occurs at low temperature
• C. The electrophile involved in the reaction is NO⁺
• D. 'B' is N-nitroso ammonium compound

Answer 1

The Correct Option is D

To solve this question, we need to understand the reaction and identify which statement is incorrect about the product 'B'. 

1. The reaction involves \(\text{NaNO}_2\) and \(HX\), which typically results in the formation of an electrophile, \(\text{NO}^+\).
2. In the presence of an amine group from compound 'A', the electrophile \(\text{NO}^+\) can form a nitroso compound.
3. The formation of nitroso compounds generally occurs at low temperatures to prevent decomposition and to ensure stable reactions.
4. The options given in the question are:
   • The product 'B' formed in the above reaction is p-nitroso compound at low temperature.
   • The reaction occurs at low temperature.
   • The electrophile involved in the reaction is \(\text{NO}^+\).
   • 'B' is N-nitroso ammonium compound.
5. The incorrect statement is: "'B' is N-nitroso ammonium compound."

Conclusion: The product 'B' formed is likely to be a p-nitroso derivative rather than an N-nitroso ammonium compound, making the last option incorrect.
