Answer & Solution
Correct Answer
(A) \(\mathrm{NaNO}_2, \mathrm{HCl} \quad \mathrm{HBF}_4 \quad \mathrm{NaNO}_2, \mathrm{Cu}, \Delta\)
Step-by-step Solution
Detailed explanation
When 3-methyl aniline is converted to 3-nitrotoluene, the following steps are involved. 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…
