NO2⏞Br→C2H5OHC2H5−Na+\overbrace{\mathrm{NO}_{2}}^{\mathrm{Br}} \xrightarrow[\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}]{\mathrm{C}_{2} \mathrm{H}_{5}^{-} \mathrm{Na}^{+}}

A

4-bromoaniline

B

4-bromophenetole

C

benzene diazonium chloride

D

4-bromophenetole

Answer

(2) 4-bromophenetole

Explanation

Solution

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.
