प्रश्न
Identify the X in the reaction.
\[\ce{R - NH2 + HNO2 ->[NaNO2 + HCl][273 - 278 K] X ->[H2O] R - OH + N2\uparrow + HCl}\]
पर्याय
\[\ce{R - NH - NO2}\]
\[\ce{R - NH - N = O}\]
\[\ce{R - N^+_2 Cl-}\]
\[\ce{R - NO2}\]
MCQ
उत्तर
\[\ce{R - N^+_2 Cl-}\]
Explanation:
Amines and nitrous acid react at 0 to 5° degrees Celsius in the presence of NaNO2 and HCI to create alcohol via the intermediate diazonium chloride.
\[\ce{R - NH2 + HNO2 ->[NaNO2 + HCl][273 - 278 K] \underset{(X)}{R - N^+_2 Cl-} ->[H2O] R - OH + N2\uparrow + HCl}\]
