MHT CET 2022 Chemistry question
Identify the x in the reaction
R-NH_2 + HNO_2 \xrightarrow[273-278\,K]{NaNO_2+HCl} x \xrightarrow{H_2O} R-OH + N_2\uparrow + HCl
Answer: (B)
Solution
A primary amine reacts with nitrous acid (generated in situ from NaNO + HCl) at 273-278 K by diazotisation to give a diazonium chloride: R-NH_2 + NaNO_2 + 2HCl \rightarrow R-N_2^+Cl^- + NaCl + 2H_2O. On hydrolysis with water, the diazonium salt gives the
