Question

Identify the reagents $(X, Y, Z)$ used in the conversion of $3$-methylaniline to $3$-nitrotoluene.

	X	Y	Z
(a)	$NaNO_2, HCl$	$HBF_4$	$NaNO_2, Cu, \Delta$
(b)	$NaNO_3, HCl\,273\,K$	$HF$	$NaNO_3, Cu, \Delta$
(c)	$NaNO_2, HCl$	$C_2H_5OH$	$NaNO_3, \Delta$
(d)	$NaNO_3, HCl$	$NaOH$	$C_6H_5NO_2$

• A. a
• B. b
• C. c
• D. d

Answer 1

Answer: (A)

When $3$-methyl aniline is converted to $3$-nitrotoluene, the following steps are involved.



Hence, $(X) = NaNO_2, HCl, 273\,K$

$(Y) = HBF_4, (Z) = NaNO_2, Cu, \Delta$
