Question

The final product of following reaction sequence is ext{xrightarrow[(2)]{(1) \mathrm{Sn} / \mathrm{HCl}} (3) $ext{NaNO}_{2}+ ext{HCl}\left(0-5^{\circ} \mathrm{C}\right)$ (4) $ext{C}_{2} \mathrm{H}_{5} \mathrm{OH}, \Delta$ (1) (2) (3) (4)

• A. (1) 4-bromoaniline
• B. (2) 4-bromophenetole
• C. (3) benzene diazonium chloride
• D. (4) 4-bromophenetole

Answer 1

Answer: (B), (D)

(2) 4-bromophenetole

Answer 2

The reaction sequence involves the reduction of a nitro group to an amine, followed by diazotization and substitution with an ethoxy group, leading to the formation of 4-bromophenetole.
