Identify the reagents $(X, Y, Z)$ used in the conversion of 3-methylaniline to 3-nitrotoluene.…
- $\mathrm{NaNO}_2, \mathrm{HCl} \quad \mathrm{HBF}_4 \quad \mathrm{NaNO}_2, \mathrm{Cu}, \Delta$
- $\mathrm{NaNO}_3, \mathrm{HCl} 273 \mathrm{~K} \quad \mathrm{HF} \quad \mathrm{NaNO}_3, \mathrm{Cu}, \Delta$
- $\mathrm{NaNO}_2, \mathrm{HCl} \quad \mathrm{C}_2 \mathrm{H}_5 \mathrm{OH} \quad \mathrm{NaNO}_3, \Delta$
- $\mathrm{NaNO}_3, \mathrm{HCl} \quad \mathrm{NaOH} \quad \mathrm{C}_6 \mathrm{H}_5 \mathrm{NO}_2$
Solution

Hence, $ \begin{aligned} & (X)=\mathrm{NaNO}_2, \mathrm{HCl}, 273 \mathrm{~K} \\ & (Y)=\mathrm{HBF}_4,(Z)=\mathrm{NaNO}_2, \mathrm{Cu}, \Delta . \end{aligned} $ Hence, option (a) is the correct answer
